I'm looking at the FIP and DIPS sabermetrics now, and I'm considering adding them to playertrack.  But, where does the calculation come from?  Details in thread... link goes to wiki definition of DIPS

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?
