Sorry for another TS setup question, but I couldn't find an answer to this on the search. This is a general question for future reference that popped into my head while messing around in the basement this evening so the numbers are made up. Let's say you set up the saw and the blade to miter slot is .002 off. Then you check the fence to same miter slot and it is another .002 off in the same direction. Does this mean that the overall setup is somewhere between .000 and .004 off or do the numbers somehow compound to be further off? Is being off in the same direction better than being off in the opposite direction? Since the distance that is spanned by the fence and blade are different, I can't seem to make sense of this in my head. I hope I asked this correctly.
