I have been fortunate to play CPC in tournaments as an amateur (Cal Am) and pro.
I Also WAS in the fortunate club of being invited for my birthday a couple times by a good friend.
Someone mentioned tournament golf vs kick around, and I certainly played differently in those situations.
In my birthday rounds, taking it left on two, driver on 4, hook off five, at pin on seven, and really aggressive lines
on 8,9,12,12,14,17.
16 is a much more aggressive shot than in most tournament rounds.
That mentality can produce a lot more excitement, a lot of birdies, and potentially a few disasters, but it is so damned much fun to push those shots in those rounds that I can't help myself
In tournaments, a bit more conservative, which does have the effect of giving a lot of opportunities and less disaster. Probably a lower average, but not as many crazy low (and high) opportunities
