From what i know sublevels arent factor for there performance but maybe i am mistaken, but even the sublvls are factor should be very small one.
So what you are saying lets say that my 2 C's have 12 on rebs, but one is 12.2 and the other 12.8 the 2nd player will be more effective? If yes how much deference will make 0.6? Thats why i said small, but again if i am wrong give us some more to understand that.
