Why outlaw bats?

[DaveASA/FED]

The way it was described to me is as follows:
ASA used a set of physicists to come up with a bat standard to remove bats that were too hot. The bat manufacturers, who have deeper pockets than the ASA, paid more for even smarter physicists to design bats that would pass the ASA requirement when new but after being “broken in” (about 100-150 hits) there coefficient of restitution changed and the bat got hotter, putting it into the illegal category. ASA figured this out and had to get smarter people to change the test method to detect these types of bats. So that is why the guidelines changed.
