[Slim Pickens]

I wouldn't worry about funky finish distributions like 20/9/8. What's more important is to look at how ROI affects the max drop. The finsh distribution itself is a much smaller effect in reality since (long-term anyway) most players have fairly flat 1/2/3 distributions. To reduce it to a simple 2D plot, I think you should do all the x/x/x distributions, where 5%<x<20%.

PS: Anyone who hijacks this thread with a "my finish distribution is nowhere close to flat" will get a "sample size snob" response unless you're raptor or FieryJustice or someone else who has at least 10,000 finishes in each place.
