What is JDC?
|
|
The Jazz Duelist's Challenge is an ongoing Jazz Jackrabbit 2 tournament where people compete through duels. 2 on 2 CTF games are also featured, as well as occasional large games which are known as "events". JDC differs from a traditional tournament in a number of ways, giving competitors as much freedom as possible.
You can duel whoever you want as long as they are also signed up with JDC, and you can duel them whenever you want. You can do as many or as few duels as you want. You don't even need to duel at all; many people participate in JDC just for the events which are hosted regularly.
The JDC website also features highly detailed statistics on a lot of things, and is almost entirely automated. This makes it very convenient and simple to use, since normal users can submit duels without any help from the JDC staff. Users are trusted to be honest with their submissions, and the administrators do their best to ensure everything stays that way.
A patch called JJ2+ is used for a lot of JDC events. It would be a very good idea to download it, as some events require it, and others are helped a lot if you have it installed. Click here to get it.
POINTS
Points determine who wins and who loses in JDC. Points can be obtained through events or duels. If you are interested in detailed information on how points are obtained, see the section on scoring.
SEASONS
JDC is organized into a series of seasons. At the beginning of each season everybody has 0 points, and at the end whoever has the most points is the JDC champion. Previous seasons are archived, although accounts are carried over so there is no need to re-register. It is important to log in at the beginning of the season though, so your account is recognized as active.
ROUNDS
Each season is divided into a series of week-long rounds. Rounds can be thought of miniature seasons, and each one is worth a certain amount of points towards your overall score for the season. Your score for each round is determined by the duels you play in; events go directly to your "overall" score. While a round is active, scores will fluctuate quite a bit. Once it ends though, the scores become permanent. See the section on scoring for specific details.
DUELS
A duel is a game played between two people. Often there is a third person who hosts. Duels are the most important part of JDC. They are what determines the bulk of your score for a round.
2 ON 2's
A 2 on 2 (or 2 vs 2) is a CTF game played between 4 people. 2 vs 2 games are considered duels when it comes to scoring, owing to their popularity.
EVENTS
An event is any game that is not a duel or 2 vs 2. They are typically hosted by officials or administrators, although exceptions are sometimes made for very small events. Instead of being calculated like duels and incorporated into your score for the current round, they are simply worth "raw" points that are added directly to your overall score. Because of this, playing in events is always beneficial, even though they usually aren't worth very much. Events are sometimes planned ahead of time, and sometimes they are completely spontaneous. They can involve any number of players, and can be any gametype. NOTE: for small, user-organized events (ranging from 5 to 8 players or so), you may only recieve points for one a day. You may still play in more than one, but for every one past the first you will get 0 points. This restriction is in place to prevent the system from being abused, and as such, it does not apply to larger events.
ADMINISTRATORS
Administrators are the people who run JDC. Check the user list to see which administrators are currently active. Because of their position, they are not allowed to win the JDC tournament, although they are permitted to participate and gain points. If you find a technical problem with the JDC site contact Bobby. For other problems, please contact EvilMike, FireSword or BlurredD.
OFFICIALS
Officials are the people who help the administrators run JDC. Their privileges include posting news, hosting events, the ability to levels to the site, and just helping out in general. Anyone can be an official as long as they are reliable, have a good grasp of English, get along with other players, and are at least semi-dedicated. Having a good internet connection is also helpful. If you fit these criteria, feel free to contact an administrator. We are always looking for new officials willing to help out. Note that unlike administrators, officials are allowed to win the tournament.

Rules of Duels
|
|
- A competitor (the challenger) challenges another competitor (the opponent).
- If the opponent accepts, then the competitors select the level, game type (battle or CTF), roast/point limit and host.
- If the challenger accepts, then the competitors select a time to duel, if not immediately. The competitors may agree to have one or the other host, or they may have someone else host their duel. It is considered rude to complain of lag during a duel. You are supposed to agree on the host before a duel, not during one!
- At the desired time, the competitors play the duel in battle or CTF mode with the agreed parameters set. For 2 on 2 games, team battle is also acceptable.
- When the duel is over, one of the participants of the duel enters the duel stats into the JDC database using the add duel page, or if it was a 2 on 2, the add 2 on 2 page.
- The other player(s) can then validate the duel by using the appropriate verify page. For 2 on 2's you can tell who has verified by looking at their name. If it is crossed out, they have verified. Once everyone has verified, the duel gets added to the database and cannot be removed without good reason. Read the stats carefully before verifying: do not verify duels which have been submitted wrong.
- If more than one game is played, then statistics for each game should be included separately. Duels must be added IMMEDIATELY after the duel is concluded. You are not allowed to submit a large number of duels over a short period of time due to the fact that it looks similar to cheating. The administrators WILL delete duels which look in any way suspicious.
- A player must participate in a certain number of duels per round to get full points, otherwise only a percentage of the total points is given. See the bottom of this page for more info.
- You are not allowed to duel the same person over and over. If you do a large amount of duels against the same person over a short period of time, expect most of them to be deleted. This rule exists to prevent cheating.
- Likewise, you are not allowed to duel people who do not play jj2. In other words, do not have your friend who has never heard of jj2 make a JDC account just because you can get easy points that way.
- Please be honest about your scores. We are giving you the privilege to send in your own scores. If this privilege is abused, players can and will be restricted from using the site, and if necessary, banned.
- You have the opportunity to write short comments on your duels. Writing unique comments is a good idea, because it tells us that the duel is probably legitimate. Please be polite in your comments, however. If you are upset about losing, take that up in private.
The JDC administration has the right to remove a competitor from the tournament for any reason. Anyone found cheating through trainer programs, by deliberately exploiting glitches, or by submitting false information will be banned: cheating in the tournament is not tolerated.

Rules of Events
|
|
- Please listen to the host of the event and any other JDC officials present. Running a large event requires everybody's cooperation. Officials have the right to kick anybody they consider to be disruptive.
- Please play with whatever name you use for your JDC account. This helps the officials know who you are when it comes to submitting scores. If you play with a weird name, don't be surprised if you don't get any points.
- Officials will often talk in colour to make what they have to say stand out. Unless you have something very important to say, please don't talk in colour.
- Events which are planned ahead of time usually have pregames that are hosted 15-30 minutes before the event. These pregames are not worth points, and are hosted for organizational purposes. Attending pregames is usually a good idea. Postgames are also hosted occasionally.
- JJ2 has a maximum server capacity of 16 connections, and events do sometimes reach this limit. To allow as many people to get a chance to play as possible, idling is not permitted. Idle players will often be kicked from events to make room for other people. Those who are kicked are free to rejoin, although they might not receive points if they join mid-game.
- For team based events, join as default team unless stated otherwise. If you leave an event or are disconnected/kicked and chose to return, please play as the same team that you were on before. Teams will be random in most large events.
- Do not complain of lag or anything else. If the event does not suit your tastes, leave. The hosts put a lot of time and effort into what they do, and do not appreciate it when they are ridiculed.
- Many players enjoy doing small events such as 3 vs 3 or 4 vs 4 ctf games. This is fine, but doing them in excess is considered unfair. Because of this, you are only allowed to get points for one of these a day. You can play in more, but you will not get any extra points.
- Some of the larger events are hosted more than once so more than 16 players can get a chance to play. The separate hostings are usually done on different days. Sometimes they will also be hosted at different times of day to account for time zones, although this doesn't have to be the case. For events like this, you may only receive points for one of them. This means if you play in a saturday event, you may not get points in the repeated event on sunday, or any other event identical to it. Sometimes you will be allowed to play in both, but you will only get points for the first one, and you may be asked to leave so others can join if the server fills up.
- Events are supposed to be for fun. Do not make a big deal out of things if you don't get as many points as you wanted, because by doing that you will get even fewer points.
- Most events are hosted with JJ2+, and it helps if the players have it as well. You can get it here.

Scoring For Duels
|
|
This section will explain how the scoring system works in simple terms. See the next section "Scoring Equations" for very specific information.
OVERVIEW
Your score for each round is determined by a number of factors relating to the duels you participate in. Each round is counted separately, and they often vary in point value and some other specific things. Your score for each round is divided into three factors: "roast : fall" points, "opponent quality" points, and "points per duel". Each of these is calculated seperately.
"ROAST : FALL" POINTS
This is the first part of your score, and the largest. Your "roast : fall" ratio (and in the case of CTF games, "points your team scored : points enemy team scored") determines the bulk of the points you get for dueling. A roast is whenever you kill your opponent, and a fall is whenever your opponent kills you. A perfect "roast : fall" ratio (meaning you didn't die once) will mean that you get the maximum amount of points possible for this part of your score for the round. Also, note that games you win are weighted more heavily towards your score than games you lost, in accordance with the "win factor".
WIN FACTOR
The "win factor" is part of the equation that calculates your "roast : fall" points for the round. Simply put, when you win a duel, it is counted more positively towards your "roast : fall" points than when you lose a duel. For the average player, this lessens the chance of them losing points after winning a duel that lowers their "roast : fall" ratio.
PLAYER QUALITY
To encourage competitors to duel more skilled players and not newbies, a system called "player quality" exists. After a participating in one full round with a total of 4 accumulated games (either duels or 2on2s), you will have a "player quality" rating in the form of a percentage, based on how often you win. If you win all your games, your quality will be 100%, and if you lose all your games, your quality will be 0%. If you have not yet met the 4 game requirement, your quality will be N/A. Note that your own "player quality" rating does not affect your score directly: rather, it affects the scores of the players who duel you, in the form of "opponent quality". Also note that "player quality" is calculated only from your stats in previous rounds: the current round is not counted.
OPPONENT QUALITY POINTS
This is the second part of your score. Your "opponent quality" score for a round is based on the average "player quality" of all the people you dueled, in the form of a percentage. For example, if your "opponent quality" averages out to 50%, and the amount of points for "opponent quality" this round is 200, you will get 100 points. In other words, the higher your average "opponent quality" is, the more points you get for it. If you duel someone with a player quality of N/A (less than 4 games in previous rounds), that duel will not affect your opponent quality score.
POINTS PER DUEL
This is the third, and simplest part of your score. Every duel is worth at least 0.1 "raw" points towards your overall score. This is meant to encourage people to duel as much as possible, and can add up in the end if you duel a lot.
CONFIDENCE
Finally, after all the above is calculated, your score is adjusted by the "confidence" factor. To encourage people to duel several times during a round, but still allow them to get points for doing only one or two duels, a system called "confidence" exists. For "full confidence", you need to do a certain amount of duels, and if you do less than that, you will only get a fraction of the points you normally would receive. For example, if full confidence is 4 duels, then doing 2 duels might get you only 1/2 of your total points, while doing 1 duel might only get you 1/4. Once you reach "full confidence", your score will no longer be adjusted by this factor.

Scoring For Events
|
|
Events are generally "weighted" to a certain score. If an event is worth 25 points on JDC, then whoever did best in the event gets 25 points. Therefore, the score people get in-game is almost always different (though proportional) to the actual points they receive.
The actual point value of events depends on how many people play in it and whether the event was announced ahead of time. Larger events will be worth more points, as well as events that have been announced at least 24 hours in advance. Sometimes, the events that mark the end of a round will be worth even more. Here are some general guidelines used for this season.
Any user-organized event with 8 or fewer players is worth 5 points. These events are officially considered "small events", and you can only recieve points for one per day. This limit ONLY applies to "small events".
Events that are organized by officials and not posted ahead of time are usually called "spontaneous events". User-organized events that have more than 8 players are also considered "spontaneous events". These are usually considered a seperate category from "small events". They are usually worth 10 to 20 points, but may be worth more if they are exceptionally large.
Events that have been posted ahead of time will be worth anywhere from 20 to 50 points, depending on factors such as the amount of players and length. 50 point events will generally be the ones that mark the end of the round. Events hosted in the middle of the round will be worth a bit less, in the 30-40 range for a full server. Events that mark the end of the season will be worth the most of all, possibly even exceeding 50 points.
Ultimately, the official who is in charge of scoring the event gets to decide how many points it is worth. They are allowed to use their discretion when it comes to this, so long as the value meets these loose guidelines.

Scoring Equations

If you are interested in the exact specifics of how the scoring system works, this section is for you. We have provided here are all of the formulas used in JDC scoring. Most people will find this to be a bit confusing, so be warned. We don't expect most players to fully understand this, but we provide it anyway in the interests of keeping our system as transparent as possible.
Note that there are three variables not listed under the definitions. The first is "rfF" which is the amount of points for "roast : fall" you see on the side of the page under "Round x Information". The second is "oqF" which is the amount of points for "opponent quality" you see underneath that. The third is "ppdF" which is the points per duel factor underneath that. That is what the note on the trailing "F" refers to.
