20 years ago Spider played pretty darn good and played a lot. Nowadays he doesn't play nearly as much because life has taken hold and he has much much bigger things going on then playing pool. How good is he now, not sure. Haven't had the chance to hit balls with him since i moved to florida a few years ago.
Question for you now. What have you changed in the last 20 years and has it helped? And how do you know it helped.
So I'll mark Spider down as another CTE user who hasn't any tangible evidence of being a better player as a result.
For myself, I continued to refine what I was already doing but also changed things up that weren't working to my satisfaction. Much of it is trial and error. I'm a better player with higher average runs and easier run outs as a result. I'm also more knowledgeable strategy wise.
