I have read all the batspeed and swing mechanics articles on this site and I tend to agree with most of the research. However, I would like someone to explain if the exact same batspeed can

This is a question that no one has ever answered to my satisfaction, and probably because the question has never been studied, at least by reputable scientists.

In my view, there are two obvious forces contributing to how hard a ball is hit, batspeed and mass of bat. Perhaps a lesser force would be the speed of the pitch. But I think the MISSING FORCE is the mass/muscle/strength of the hitter himself. I have a hunch that in a scientific setting, if you had a group of 100 hitters of equal skill, athletic ability, mechanics, etc, and assuming they all had the same bat weight and batspeed, I submit to you that on average the heavier guys would out-power the lighter guys.

We're talking theory, now. Black Hole Lexciographer, comments about me picking on the small guys are not welcome. It's just a fact, common sense that size has to be a factor, however "big" or "small".
