I've been an APA 7 in eight ball for years. I have probably been on the low end of the sevens in terms of skill the entire time but managed to eke out a winning percentage over the years. Now at age 72 my fire power is apparently diminishing and even though I have had about a 20% win ratio over the last few years, I remain a 7. Does anybody have any insight on what it takes to move down a notch? Thanks much.
