I haven't notice taking a 3W off the tee on Kiawah Island affects your driving stats, of course I haven't used a 3W off the tee there.
Note Kiawah Island is not the problem, it is BethPage Black. Please read my previous post carefully. It indicates the driving accuracy is based
Kiawah Island. I just finished a round this morning at BethPage Black. Every fairway hit in regulation, with an overall driving average of 86%. Now, looking at the symmetry of both courses, the only difference would be on the front nine. A par 3 on the third hole versus a versus a par 4 and a par 4 on the fifth hole versus a par 3. Thus, 14/16=87.5%. Now, I did use a 3W on the 4th hole, but it showed up as a fairway hit on the scorecard.
