I'm probably inspired by what I've read around here and elsewhere, but...

I think from having the weight more or less even distributed on both feet at address, with enough weight toward the heels for the player to be able to lift the toes, the backswing pivot loads pp#5, the inside of the heel on the back foot (~2/3), and pp#6, the inside ball and partially the big toe on the front foot (~1/3).

A line between these 2 pressure points corresponds pretty much to the amount of hip turn, and can be used for direction of the hip bumb/axis tilt for the hitter.

Through the downstroke the pressure shifts gradually until follow through to the opposites on each foot: pp#7, the inside ball and partially the big toe of the back foot (~1/3), and pp#8, the inside of the heel on the front foot (~2/3).

Again a line between these 2 pressure points corresponds more or less to the amount of hip turn (roll).

During the finish swivel going to the finish, the weight comes to rest even distributed on the front foot (~9/10) and on the toes of the back foot (~1/10).
