After a good days practice on the easiest 9 holes at WGT, with a gifted set of the best possible clubs and a good sleeve of balls, I could understand, however unlikely, an "experienced" online golfer, even if not a "return WGT'r", assembling such an astonishing first ranked-round from the Hack tees on Kiawah's back nine.
The saved replay shows that there indeed was practice, and that that practice was on the same back nine that the "stellar" ranked round was achieved.
It surely is incredible, but stranger things have happened. Maybe not probable... but possible.
The stat's merely reflect that one unbelievable ranked round, so naturally they'd be nearly perfect.
What I find even more incredible, is the ability to come within a stroke of this score, while using the starter set of clubs, but, to date, 3 have accomplished that, with one of them doing it also, in his first attempt.
