I can easily tell if I am getting better or not without keeping a score or maintaining a handicap! That's cool that you are in to stats and what not and I know many like to know that stuff. Every player I have ever know whether good or bad plays differently every single round they play. They will hit 5 fairways one day and 10 the next, have 28 putts one day and 40 the next, hit 2 greens one day and 18 the next, ect..... While it may be good to know what your stats are, in the grand scheme of things it all comes down to execution. I just have a hard time buying in to a system that tells me "on my best day I should shoot XX", while maxing out scores on a hole based on what your handicap is and throwing out bad rounds. Almost every player I have ever played with has never shot that score they were "supposed" to shoot.
