It depends. My mate won his first club championship when he played off around 13 or 14. His first round was level par (1 over SSS). He had a genuine earned handicap before the club champs, and maybe been a member for a year or two. He is a naturally sporty guy, and he would have started to play and practice a bit more in the weeks leading up to the Club Champs, like a lot of players do. So, the Club Champs along with the practice just lead to him refining his game, and ultimately led to him beginning the process of falling towards a handicap of low single figures (think his best was 4 or 5).
So, just because someone shoots nett 10 under, it is probably fair to say, doesn't automatically categorise them as a handicap cheat (as per the thread title). They could just have a genuine reason to have significant improvement, coupled with a round that went extremely well for them in terms of luck.
Perhaps i'm miss judging how hard it is, but i would have thought someone playing off 4/5 over 5 years (so true 4/5 handicap) will have shot a 69 at some point. I mean it's 7 or 8 under but i still would have thought it happens as they've got the ability to par every hole if they get on a run and manage to keep it together mentally.
