Maybe slightly but anyone shooting 940 is playing pretty much flawlessly so who knows how much the table has to do with it. Most of the elite players are hitting center pocket more often than not.I think TPA's are at least slightly and maybe considerably relative to the rules and table conditions. So a .940 on a 4 3/4" Gold Crown, with template rack, and 9 on the spot, is different then that same .940 with the Matchroom version of 9 Ball on a tight Diamond.
***edit***
I know they didn't use templates back in the day. Just using that as an example.
Some say those matchroom tables play pretty easy with the new cloth. I have seen many balls that went in matchroom events that would have had no chance on a 4.5 diamond with worn cloth.
