BullShooter,
This question might be better for the main forum.
However, the answer is yes...& no.
Once one has reached a certain level of knowledge & proficiency to execute that knowledge with a relatively high level of consistency, naturally there is a plateau until new knowedge comes along. When that new knowledge does come along, one can work to improve one's game.
In the mean time one can only work to increase one's consistency of executing what one knows & look for more knowledge.
I hope that answers your question to some degree.
Naturally, I have hit plateaus. I have been on one for quite a while until CJ Wiley came along & brought up some 'food for thought'. I am now in the process of trying to elevate my game even though I am 59 years old & will probably do nothing with it but enjoy myself maybe a bit more & maybe have more information to pass on to others.
Best Regards & Good Luck in your search for & on your journey to improvement,
