Wow, just perused the stats of a lvl 28 Amateur, and was very impressed.
14 ranked rounds, 90 odd birdies, 90 odd pars, 3 eagles and 18 bogies.
Putting stats a drool-worthy: 5-10 ft @22+%, 10-25 ft @12+%.
This player came to my attention in an RG tourny with heavy conditions. He handed in a card similar to many skilled and experienced players.
Club selection is indicative with someone who has played the game before at higher lvls. Driver, irons, and WGT ball, but house putter and wedges.
I would hope that double account players are found out at an early stage, so as to avoid them stealing winnings off of honest players.
