Just to clarify something, JDC would not necessarily end, it would just be put on hold. Think of this tournament as an intermission.

Here are some examples of possible bonus rules:

If you are in the top 5 for 4 continuous days, your are immune from being cut this phase.

If you are idle for 3 continuous days (no duels), you give 20% of your points away, divided evenly amongst others.

If you win 5 duels in a row, your rank increases by 5 (by adding an appropriate amount of points to your score).
