Stats, I hear what you are saying, but even with data on what happened on every pitch on every 3-2 count, that does not take into consideration whether that pitch was a 50/50 pitch or a pitch right down the middle belt high. Until that can be quantified, you can't tell the effectiveness of taking or swinging at a borderline (50/50) pitch. We can theorize about it, but you can't back up a theory using data without knowing whether every single 3-2 pitch was a 50/50 pitch vs. a definite ball or a definite strike.
