I'm shooting in the 70's now. Anything over 79 is a bad day. I play a couple times a month and practice when I can. If I could get out more I know I could go low. I've got to get my priorities straight!!! So for a middle aged guy that took up the game late in life and has been golfing 8 years, I'm very happy with my decision to base everything swing related on TGM.
I wonder how many other books/authors could say the same-8yrs experience and shooting 80 on a bad day? Full credit to the AIs of course.
