Some findings so far (I only played online CTF matches):

When playing CTF online with the lowest possible packet interval rate, the game basically couldn't be any smoother, when it comes to player movement of remote clients and overall experience. That combined together with having the bullet reporter settings of server and victim enabled makes for a game that at least from my perspective is lag-optimized to the maximum.

Basically such a game has all the weird lag issues eliminated, that typically happen in a friendly/competitive CTF match, like players getting hurt/roasted by bullets that looked like they were far from being a hit on their own screen or remote players moving in a jerky way on local screen. I think having the victim-setting enabled as a part of the bullet reporters-feature plays a big role in ensuring that you always get hit from bullets that you land on in your local screen, which further seems to eliminate the typical "bullet bouncing without taking damage when should"-cases that happen in online games. However, I think it is good that the server is not being fully ditched as being a "secondary" reporter, so that there won't be too much of a synchronization issue between those clients who shoot bullets and those who touch them.

So, I would say that lag-wise I am really happy about how this combination turned out , but bug-wise there are some things to take a closer look into.

One of the bugs seems to be, that springs (randomly?) stop working for certain clients middle of the game. This did not occur to me yet, but on one of the rounds I had 2 other players, DanZeal and Spyro, reporting about springs not doing anything. I'm not completely sure if the springs in question started to work again later on or whether it was all of the springs or only some of them. If more input is required, I suppose Spyro and DanZeal can be contacted, e.g. on Discord. Also, based on the rumors I heard earlier, e.g. from ak-47, it seems like this is something that has happened already on the previous build of bullet reporters w/o pxinterval-changes, but I don't recall who experienced what. I think Kev might recall this better too?

Another bug that happened to me personally in-game, was that I seemingly went from 1h to 0h and did not die or respawn, after taking a hit from a bullet. The issue resolved only after taking another hit from a bullet that finally ended my "zombie mode".

I recorded several rounds of my CTF games, but only uploaded a few of them onto youtube so far. Anyway, here are 2 good examples of the findings:

https://www.youtube.com/watch?v=qvHMEUwdM3g - On this round we played with the lowest pxinterval-rates and with ONLY victim-setting enabled. DanZeal and Spyro reported that their springs stopped working mid-match, around 4:30 video-time marker. Also what ak-47 writes in the chat at 5:55 may or may not have something to do with the bug that I experienced with having 0 (or negative?) health and thus DanZeal was not able to pick up carrots when supposed to.

https://www.youtube.com/watch?v=ACrk3wEN4E4 - On this round we played with the lowest pxinterval-rates and with BOTH server- and victim-settings enabled. Around 1:00-1:15 video time I experience the bug regarding health I mentioned above.
