I think anyone who can HONESTLY shoot below 100 is doing something right. Im a 13 year old junior and i usually shoot in the mid to low 90's, and on a good day i might just barely scrape into the 80's. And these scores are with not counting the odd 1 that goes in the woods or redoing an absolute duff of shot. In tournament play i seem to shoot the same as i do normally without all these mulligans ect. but i think thats just competition bringing out the best in me, CURRENTLY i don't think i could honestly get a 90's score consistently keeping proper score. So in my mind if you can break 100 keeping proper score your doing pretty good. FYI i shoot from the white. And just to add on another point, my older brother, who is in his mid 20's, and who i golf with 2-3 times a week, can hit it upwards of 300 yards, drive the green on some short par 4's, has a decent putting/chipping game and so forth. But every one in a while he'll fire 3 in a row into the woods or duff a couple shot and end up with a quadruple bogey (he shoots low to mid 80's) so the line from a okay golfer to a good one is very fine.
