iukine: What's your criteria for regular scores?
I'll give you numbers as it pertains to me on 9 holes...
Excellent is 27
Very good sub 30
Good 31-32
upset is 33+
Of course wind conditions play a part...i/e front 9 SA RG in low winds, a 30 isn't "very good" anymore, but becomes "excellent" (for me) in high winds.
Keep in mind 99.9% of my stroke play is RG's or CC tourney's.
So in my opinion, based on how I play said tourney's, I'd say my "good" would be my "regular".
That's just SA though.
