I guess it's not impossible that he crumbles under competition pressure.i saw the R&A put out a notice about promoting honest and fair use of WHS today....

I was reminded about a guy in my club who falls in to the "vanity handicap" category so had a look at his scores.
He is 5.8 Index - all his counters are General Play. His competition scores would give him a 14.4 index. Why would you do this to yourself ?!
