Re: how do "you" define high, low, mid handicap golfers?I'll try a slightly different take on the answers:
High Handicap - Missing most swing fundamentals, and doesn't understand much about the swing. Occasionally gets a par or a very rare birdie, but mostly just tries to get the ball around the course without too much trouble. Tough courses won't be much fun. Index is probably >25 or so
Mid Handicap - Has some decent fundamentals, but still has some fundamental flaws in swing that reach up and bite hard. Doesn't quite understand the swing enough, though, to diagnose those problems and fix on course. Gets a number of pars and knocks in the occasional birdie. Has a number of blow up holes each round, though. Can place their shots just enough that they're starting to see the course strategy, but not consistent enough to take advantage. Index range is pretty wide, probably about 5 or 6 up to 25.
Low Handicap - Pretty solid fundamentals, with only an occasional problem that causes a wild shot, but skilled enough to limit the damage and rarely more than one blow up hole if any. Understands a lot of the swing and can diagnose enough on course to keep things on track. Understands course management, and has just enough game to look strategically at shots and execute what is needed most of the time. Can play any course in the world and enjoy it for how the designer intended. Index is around a 0 to a 5 or 6.
Scary Good - Repeatable swing with predictable shot shape. Can shape shots as needed. So consistent that course strategy is the major factor between scoring well. Bad luck is probably the biggest contributor to having a bad hole due to a funny bounce. Score is probably influenced the most by the putter - some days they just don't go in and he shoots even par, while some days everything goes in and shoots a 66. Index is +.
