Well john, I suggest-practice-unranked-games-experiment with left-right-meters-
putt from fringe-change the foot increments- with practice and mulligans, try to ingrain memory for feel and timing.
try chipping and pitching with different lofts off green, half swings-better chipping means shorter putts!!
We were all there, patience will go you to a better place.
anyway, practice-gl
