Flash, don't doubt your experience down there. Maybe my 5% is a little low, but I really don't think 40% of people hit 12 v 2 in lower stakes in AC.
Would guesstimate that 2/3 of players at this level are newbies or people who play very infrequently, and they almost never hit 12 v 2.
Of the other 1/3 who play more frequently, maybe half of them might hit 12 v 2. I'm still surprised when I see someone play BS perfectly. Even those with BS cards don't sometimes
I could be wrong, I'll be in AC for a few days very shortly, so I'll make sure to keep a closer eye on this and see what I find.
