Here is the formula for FIP: (13HR+3BB-2K)/IP
HRs, BBs, Ks, IPs all happened, correct?So FIP is based on things that happened (facts) as is ERA (ER/IP)*9
They are both factual measurements.They just measure different facts and have different uses.
I would disagree because Out of Zone swing percentage is simply times swung/oppurtunities to swing.In no way is it debatable how many times Dozier swung at balls and how many times he didn't.
What if I were to argue that the formula would more accurately be represented by a 12HR variable?Whole #'s across the board seem really unlikely to be the "true" impact of these events anyways.This is likewise with WAR.The balance of fielding vs. hitting vs. running is not a settled debate, that's why there are different measures of WAR out there, because it isn't fact.
Don't get me wrong, I like FIP, but since the impact of fielders and wind and so many other variables are not completely understood, it is not fact, it is theory.
