I floated around 0.5-3 for years in my mid teens and early 20s. I now shoot mid 70s to high 80s, but I rarely play now, maybe 5 times a year, and the big difference is my short game. I use to get almost everything up and down inside 135 yards (pw), or at least gave myself a 15 footer, but now I might fly the green and leave myself on the wrong side of the pin. the game is is still there because I can still go 1 2 under on a 9, but I'm just as likely to go 42 on the other 9. Just no consistency inside 135 now. long story short, track your numbers inside 135. are you knocking it down in 1-2-3 shots. You need to eliminate the 3s by leaving it on the right side of the pin. I have a bit of distance that still hasn't gone away (can still hit 280 off the tee, and 250 with my 3-wood, and hybrid can go 220) but use to be 20 yards longer in my late teens/early 20s. at the end of the day, it's my short game/wedge game where I lose almost all my strokes.
