On the contrary TMPC, real golf knowledge has helped me immensely in this game. While the physics are off a little, they have definitely helped with trajectories, club selection, and anything around the green regarding lie management. Not sure if you are surprised but many a top player on the site are very good golfers in real life.
OP, where are you falling short? You want tips? Help us out, where are you losing shots? You want my 2 cents based on your stats page? Here you go:
1) driving is fine, right where most of the better players, nothing to change except that perhaps you might want to risk hitting to spots that give you a better approach angle
2) approach, you need to get this stat up. More greens, equals more oppotunities at biridie, and if you miss should leave simpler pars.
3) putting, (A) you bought the other clubs, dump the beginner putter, forget accuracy, a better putter has an easier meter with a shorter putt distance. a 6ft putt is easier to gauge on a 15ft meter, then a 30ft meter. You should notice less lip outs with the better distance accuracy. Hopefully that alone can save you that dumb 3 putt every now and then (couple strokes saved per round). (B) Its easier to putt from shorter distances. Improve your approaches is one thing you can do. The other thing is your work around the green. We all miss greens, but anything but a short chip to a severly downslope should be an automatic up and down. Work your chips, pitches and flops. Use back spin to check the ball. Figure out those distances, what checks, what rolls. Flops are helpful. Leaving yourself less then 5ft for par versus 10ft for par should shave off another few strokes.
4) You are in a CC, yet you rarely play match play. Start playing more with others, preferrably friendly better players. Watch there shots, watch the swings, watch the club changes, and ask them how they did something.
5) New advice from me since I rarely did it before. Play CTTH format. Its great at learning different shots, and it takes minutes to complete, and you can just click replay to start again to try those exact same shots over and over, its actually a great practice facility
Thats all from me
