Not sure if Tom Tango did any pitcher equations. Those first two pitcher are equations I got from J35J, a cafe poster. The second two are my equations I used by altering J35J's to fit my HTH league targets. You could PM J35J here and see where he got those

This is the first year I've played with using a ranking equation, since I'm doing auction leagues for the first time. I've thought about doing it, since I'm a math dork, but never took the time to implement anything. My conclusion was that these could create positional rankings pretty well and then I had to come up with a way to adjust for positional scarcity based on incremental value above/below an average fantasy starter value for each position based on league structures (how many players of those positions I expect should be starting on fantasy teams).
