Anything in specific...haha
Lower the compression, the hotter the bat...that's the basic translation. Old school numbers used to be USSSA passing is 225 and ASA is 1550 (now there
are so many variations of passing numbers depending on bat). That's why testers really need to have their sh!t together.
Each bat is different as to improved performance and there is no way to give exact numbers. Who the heck knows how much better the bat is
at 265 than it is at 275. The point is to stop the bat once is hits failing. I know from experience, there is quite a diff in a bat that is at 275 and then at 225.
I have seen bats under 100...and they are lethal. That's why they do this. Its not perfect, but its better than what was ever out there to stop certain things
You have bats now that have thinner walls, but internals that keep the bat from failing...which is why they are granted a lower compression number than others.
Old school bats like the Eastons and such, would start high as hell...like 350-375. Then just keep lowering, and never stop. Which is why people loved the old Eastons.
They knew the bat wasn't legal after a while but they weren't "cheating" as long as they weren't testing. Those things would get super hot!!! But a lot of old bats did that.
As for altering...this was a big reason for testing. A new shaved bat may pass the first tourney...but wont last much after that. Seen them pass initially, then fail by
the end of a day.
Btw, using usssa numbers as its easier
Easier to answer specific questions that just ramble on and on.
Because that bat was a terrible bat...haha. That was Eastons pre-tester attempt to curb people altering bats....
