Easily enough to match the competitions that my club was offering. I belong to a society that plays ten times a year, and I can easily add 20-30 opens on top. I've been through the listings on Golf Empire and created myself a couple of itineraries (one that is all individual, and one a mix of individual, pairs and team). Add in a handful of social rounds (I mainly play comps) and that's a full year for me.
I played 39 rounds of golf last year but only 19 of them were at my home club. That's about £48 per round for the home fixtures. If they organised more competitions, I'd enter them all; but they don't, so I'm leaving.
