D2 and D3 show roughly .75 unearned runs per game in both '10 and '11. If you switch the D1 runs scored figures, they'd show roughly 1 unearned run per game both years.

Good catch. I should have checked the data prior to posting it. The stuff I posted was given to me by a local college assignor. I went to the NCAA Arbiter site just now to verify and found the mistake. I gave you the credit for finding it when I sent him the news.
Here are the final NCAA stats after the new bat rule went into place.
D1:
Runs Scored 2011 =
5.58 per game Runs Scored 2010 =
6.98 per game
ERAs 2011 = 4.67 per game ERAs 2010 = 5.95 per game
D2:
Runs Scored 2011 = 5.78 per game Runs Scored 2010 = 6.75 per game
ERAs 2011 = 5.04 per game ERAs 2010 = 6.08 per game
D3:
Runs Scored 2011 = 5.90 per game Runs Scored 2010 = 7.08 per game
ERAs 2011 = 5.13 per game ERAs 2010 = 6.30 per game
The NCAA site also has a qualifier below the stats, "Averages are per game and per team." I can see why he included it but was not confused.
One year of data is not perfect but almost every coach I encountered agreed that the BBCOR bats made a huge difference. Slap shots become manageable groundballs. The 5'5" second baseman wasn't hitting bombs and the pitcher had time to react.
