If it technically isn't there, then it isn't there.
If there is no evidence of something being in the game, then there is no reason to think that this something is in the game. If there is no evidence of a hidden attribute that we don't know of, there is no reason to think that it exists. Burdern of proof etc.
Would you take my word for it if I said there is a currently unknown statistic that affects hit rate, without wanting to tell anyone how i found this out?
