Not looked at it but would guess around 6-8 per round. Trouble is I am chucking some big numbers in on a couple of holes per round which with the odd double and bogies means I am struggling to make buffer zones by a shot or two.
Since October, I've had between 7-12 pars a round according to my stats. If you call that 9 as an average, I then add probably 7 bogeys or worse and 2 birdies which have given me scores of 71-82 during this time.
The 71 had 9 pars, 5 bogeys and 4 birdies. The 82 had 8 pars, 5 bogeys, 1 birdie and 4 doubles. Seems I'm always getting the pars in, it's just what happens on the other 9/10 which decide my fate!
I would expect an 18 handicapper to average 3 pars a round. Adding to that maybe 10 bogeys and 5 'others'. But that's purely giving it 5 minutes thought at my desk ...
