GJB,
I think the Current Australian system, certainly allows a 21 marker to beat a 6 marker. 50/50.
I believe we are about to tick over to our new system next week, a combination of the USGA but have spent the last 4 years adapting it to the Australian way, which is mostly competition golf, where all rounds are handicapped.
Can someone confirm, that in all the discussions above, each different set of tees is rated separately, so usually a longer set of tees will be rated harder?
