I would say that those percentages would lean greatly towards being negative though, you were simply fortunate, that's all.
No different to people stating there average driving distances or best iron distances into the greens, when 7 out of 10 times most handicap golfers will be short, that's because they only remember or want to remember there best shots with those clubs!
With any clubs! We have to hang on to the memories of the good shots or we wouldn't go back. In psychology, it's called positive reinforcement. Have you ever noticed that towards the end of a particularly bad round you get one or two good ones in? It's all part of a cosmic conspiracy to keep us golfing, to keep us suffering.
