I think batmakers should press the life out of the bottom inch of a bat so it's like concrete to stop it splitting
I think maybe the fact that on a machine a bat is pressed quickly and with so much force that you get a better bat if it's softer and made firm enough for use in match by by a round mallet, the pressing isn't as deep.
I also think a lot of people don't knock their bats in long or hard enough. I see people with new bats and 99% aren't fully knocked in. When I tell them they say yes it is. I go to my bag, get out my round mallet, hit it with 75% force and sure enough there is a dint in the face. Most are astonished as they spent hours using a flat mallet. Start with the flat until you are blasting it full pelt, then go 50% with the round mallet and work up the strength.
Completely my own thoughts so I could be talking rubbish again.
