Stratos, regarding those very pretty MS Paint curves--you can just do that by capping nBattles.
COIL doesn't seem to support that, but that seems like a pretty good idea.
My approach with formulas is always to make the numbers mean something.
So how I think COIL could be configured is by two numbers:
1. F = GXE floor
2. NF = number of battles a player at GXE floor needs to play to qualify
So, if F=75 and NF=100, a GXE 75 player would need 100 battles, a GXE 80 players might need 80ish, a GXE 90 player might need 40ish.
We modify the COIL formula to cap N at NT, which will give us pretty much exactly the second graph Stratos posted.
And then we can plug in GXE=F, N=NF, and solve for B.
Then, tier leaders can announce F and NF and minimum COIL, and then those numbers are a lot more intuitive to the players, too.
@ blarajan: the only uncivility in this thread toward a ps dev has been towards slayer95 and he really brought that one on himself, theres no need for tone policing :|
I've definitely been in way ruder threads (I'm still kind of bitter about the teambuilder tiering one), but in general there's at least a fair amount of entitlement in these sorts of threads.
Pretty much everyone's attitude here is "This is what I want, give this to me" rather than "This is what I want, how can we reach a compromise where everyone's happy?"
