Tom Tango's FIP statistic has caught my eye as a potential addition to PlayerTrack to scope out more effective pitchers than their numbers suggest.
So, I'm staring at the formula, and I'm wondering what do these numbers mean? I haven't seen any rationale. I suppose I could buy Tom Tango's book, maybe, and this would explain it?
Look at the FIP formula.
FIP = ((13HR+3BB-2K)/IP) + 3.20
Why multiple HR by 13? Why multiply BB by 3? Why add 3.20?
There is certainly a method to this madness because we are dealing with some statistical giants here... someone fill me in on the logic?
