Say you were indeed ace hunting in the scenario DiscFifty presents. You know after your first shot on hole 18 if you aced or not. Could you just walk off and DNF at that point? Feign an injury or something and say "hey, can't finish" ?
Simply curious. I absolutely wouldn't condone such a thing.
I'm even wondering one step further, if you complete all 18 holes and then ask the TD to DNF, can the TD PDGA legally add a DNF at that point? (regardless the reason, just wondering if the system allows this.)
