You are a casual player.
those top players use up to 6 hours a day to get those scores, less when they know every inch of every green.
I can putt a few from memory on most courses, I have only played 1300 rounds, I promise you when I have played 3000, I will have most of the putts down on memory or notes.
Only just started to take notes.
I played the same course 4 times today , and had the same putt 2 times, I did not make the same mistake twice. that is what I mentally noted.
Will remember that one, and took notes on it !
JUst accept that some try harder than you !
