That's because there is no possible twist of logic that can make this a reasonable act. Your buddy got screwed by a clueless handicap committee. No possible justification for what they did. There is no fairness or logic in modifying a player's handicap on the basis of a single score, and doing so because of a single scramble score is sheer stupidity.
For one thing, a net 62 is not an exceptional scramble score, at least not in my experience. If it was a two man team competition, then 62 is pretty good, but it's still a scramble, and as such, a lot of really bad shots get tossed and never count for anything.
Something is very not right with your club's handicap committee.
I have one that sits in the corner of the garage now ... I think I paid $350 for it ... through this site I learned you can't really "buy" a game off the shelf. So I took the Edel challenge ... I went and got fitted ... the BEST singe club decision I ever made.
I will add ... my Edel putter combined with an aimpoint class, has me putting like a low handicapper. Could not be happier.
