Subsonic What about a match play situation? Last player standing is the best.
Golf isn't like other individual sports (tennis, for example) where the better player will win almost all of the time - even the very best players will lose an 18-hole match to an average tour player once every three or four times. There's not enough talent differential between the top players, and there's a lot of natural variation in scoring in golf (the putts that burn the edge versus going in, the approach shot that catches the right or wrong side of a mound...)
(By contrast, there are seasons where the top tennis players have won well over 90% of their matches - Connors had a 93-4 year, Federer 92-5, and Graf had a 3-year stretch where she won over 200 matches to 7 losses. It's a lot easier to determine who is the best player when they're playing that many matches, of course - how often do you get a true head-to-head matchplay situation in professional golf?)
