If players have the same number of points/$ their highest placement in any (or more) tournaments comes into consideration. Meaning if 2 guys for example have let's say 200$ and both have 0 1st, 2 2nd place finishes the 3rd place finishes make the tiebreaker. This would reward results and not participation.
Tis also eliminates extra tournaments since it's like super unlikely 2 players have the same cash and exact same finishes.
