Look Dojji, I completely understand the math. But I think you may be misinterpreting what BABIP is intended to measure. I read a fair amount about it in relation to Buchholz's 2010 season. He had a very low BABIP that year, an unsustainable BABIP, which indicated that he was very likely to regress the following season. It was all about the number of balls that got put in play against him and how relatively few of them ended up as hits. That is the percentage it measures.
