The rationale for the 2013 ASA stamp
The exit speed threshold for bats to be approved by ASA is 98MPH.
To calculate that number, a formula was developed that measured several different variables about the bat, the ball, and the swing speed of the bat itself. The swing speed was calculated to be an "average" of all players and set at a certain number to be used in the exit speed calculation. In 2012, several field studies were done around the slow pitch game and it was discovered that the number being used as an "average" swing speed in the calculation was higher than what was being discovered in the field. As a result the swing speed number in the bat exit speed calculation was replaced with the number from the field studies. This allowed bats that would not meet the 98 mph standard with the higher number to now meet the standard. These are the bats with the 2013 ASA stamp. So the "hotness" of the bat depends on how hard the batter swings and how solid the contact is between the bat and ball. As a side note, I have learned that a Men's FP league in my area has decided to only allow wood bats in their league this year.

On topic: Good to know this forum (and my area) has people knowledgeable about bats & balls news. I just show up and work and make sure the equipment is legal and reasonably round. Back off topic: The orange 2015 Easton Mako bats are the hottest bats I've seen in a long time (comparable to the doublewall Miken bats that were legal around 2002 but banned after 2004 or so). I saw a check-swing slap hit home run over a 220 ft fence last week...with poor contact on a changeup out of the strike zone. The batter ran to first base and over-ran it, thinking it was an outfield single, and knowing she barely swung.
