marioh: This idea is to stop sandbagging for credits. This applies to Net credits earned, so that would be net credits earned through free tourny winnings, match play challenges, and RG's.
There is such a very wide discrepancy between the payouts of free vs RGs and between the frequency of free vs RGs tournaments. You will end up making it impossible for those who can't participate in RGs/MCs to move up in tier. Someone who doesn't play tournaments at all is out of luck. Stuck forever in the Pro tier. (wait...doesn't sound too bad, LOL)
A RG winner wins 5.50 and nets 4.50. You can play how many per day? 3 or 4?
A free tournament winner nets 1.50 - 1.80 and can play 3 per week
A free multi-round winner nets 3.15 and can play 1 per week.
Theoretically now, to show the wide gap, if one wins all of the 4 RGs entered each day, net weekly winnings is $126. If one wins all the free tournaments in a week net earnings is: $8.55
The more I think about it the less I like the idea of including earnings. Base it on what scores you shoot, not how much you earn. If you're shooting low enough scores, a good system should take care of it.
AvatarLee presents a workable start on a good system, IMO, in this thread
