Probably 10-15 hours per week, student out of school for the summer :D
EDIT: Forgot to add that I'm a Master.
Pro............14-18 hours a week
Master
Around 5 hours a week nowadays due to nice weather, baseball, Sims 3, and being bored with the game.
That number will probably continue to drop unless some changes are made.
Pro- ankle injury so 20 to 25 a day. Will decrease in about 3 weeks when back to work
I ment 20 to 30 a week
Laid up after knee surgery and can't play real golf. Discovered the site about 5 days ago. Ranked as a pro but have only broken par once. Been playing about 6 hours a day. My swing meter skips a lot and cost me a shot at the Pilsner crown. Had 47 total feet through seven holes and racked up 150 feet on the last 2!
3 hours a day enough to wear down my left mouse on laptop .
