lol, you are horsefeathers troll. I was responding to the dude who thinks we've cracked the code.
Data are data. The information upon which a decision is made is interpreted and not free of subjective determinations based on "gut" feeling. For example, saying Bellinger is a 120 OPS player and PCA is an 88 OPS player is not based in reality either, because it's projection. Is it better than a cold guess? Sure. How much? we don't know.
The thing about ZIPS is that in aggregate, the information on team performance is pretty good. The prediction of individual performance is not that good, but over and underestimations are normalized acrosss the individuals, for the most part.
