Just my guess, I would thing the Blast Factor is ball exit speed maybe?
Looks like my guess was wrong.

What is Blast Factor?
Thanks for posting the link...but I still want to SEE how it's calculated.
Or at least see a visual comparison of 2 swings and see how the Blast Factor is used to compare those 2 swings.
I'd like to see Miggy vs. Judge in a Blast Factor Showdown.
