I know that it's been the proverbial hundred years since I was in school, so could you please explain that new arithmetic of yours for me, explaining how the fellow who missed his starting Par 2 hole gets a 12?
He missed the par 2, so his score was 6 on it.
He parred the par 6, so his score was 6 on that.
For the two holes combined, he got a 12.
The player who missed the par-6, and parred the par-2, also got a 12 on the two holes combined.
