I probably average one every other round on paper, but it really varies. Sometimes I'll go two or three or even more without one, then I'll have a round with a couple of them. Shot a ridiculous 85 a couple months ago - I say ridiculous because it included a record 4 birdies for me and should have been about a 77 if I hadn't have totally lost the plot for about 6 holes.
The short answer is that it entirely depends on how I'm rolling the rock that day.
