You should have reviewed the link he posted a little closer.
8-Ball
7' - 44%
7' - 52%
9' - 49%
9' - 50%
9' - 54%
All of the 9 ball he had listed were 9' and varied from 16% to 37%.
Statistically speaking of course, it looks to me that 9' had the highest run out percentage by a 3% average.
Ok - US Open 8 ball was on a 7'.
So, here's the math:
Mean runout percentage for bar box = (52+44) /2= 48% average runout rate.
Mean runout percentage for 9' = (50+54)/2 = 52% average runout rate.
Net difference - 4%.
Taking the high/low results, we have anywhere from a 2-10% difference in BnRs from a 7 foot to a 9 foot table.
I'd say there is a statistical difference. I threw out the Chinese 8 ball because it's a different table, entirely.
The difference between the #1 golfer in the world, and #100 is just over 2 shots per round. Less than a 3% difference. Statistically very different.
