Every year from 1995-2004 I would write Dean Knuth (the pope of slope) a letter regarding issues with the USGA handicap system as we knew it. Many times would follow it up with a phone call which would invariable end with a thank you Mr Struthers for your interest. He never seemed to think my ranting about the use of potential as the key element was inherently flawed.
Think about it you shoot 71,69,76 81,80 84,77,72, 75,70, 80,70,72,79,79,73,83,70,76,71 for your twenty scores
your friend shoots between 72-75 for his 20. who's the better player he is, who's handicap is lower, yep the guy who shoots 80's on occasion
Remember this is with equitable stroke control which brings your scores down by scotching out the big numbers.
Now we go to best eight rounds .....really
If people are going to fudge their handicap to win you can't stop them with rules to figure out potential so just let the committee throw the really bad guys out once in a while or at least threaten it !
