OK, the ASA needs to clarify this...

This statement seems to say it all.

Again, this does not even come close to a perfect solution. The more you take 'legal' at bats and BP with a composite ASA bat, the more the "fixed at the time of manufacture and may not be altered in any way thereafter" characteristics of the bat change! Do you guys really mean to tell me you don't know what happens to composite bats the longer you hit with them?

The walls become thinner due to loss of material from repeated impacts with 'legal' BP and game usage. You can hear the material rattling around inside the bat (this is resin/glue and composite material from the bat itself)! The bat hits the ball harder and harder with the same swing speed and same incoming pitched ball speed, resulting in a higher true batted ball speed. This batted ball speed increases as the overall life of the composite bat decrease (sometimes proportinally, sometimes not) The bat is altered physically by exactly following the ASA guidelines!
