I watched both Back Arm of 4 Great Hitters & Pre-Launch Batting Mechanics Bonds & A-Rod.

From "Back Arm" video, you explain Ken Griffey Jr's bat speed. Keep his elbow back as that forearm rolled. He is gonna pull back with the back elbow and allow lead shoulder to apply that force. Now this is what is really make this bat to really take off.

From "Pre-Launch Batting Mechanics Bonds & A-Rod" video, you explain about Bottom Hand Torque at the end of video like this:
Now, notice how their back arm hardly moves. It just rotates with the body. So the real pull, coming from and the torque is being applied as the bottom hand is gonna driven forward by the rotation of the body, noticed elbow didn't hardly move at all in either case. So what is actually cause the torque that really supplies great power at contact is the rotation of the lead shoulder through the lead arm and that's why it has to maintain a solid angle to be able to give a good solid pull to contact.

From "Batting Instruction: Bottom Hand Torque" you explain Bottom Hand Torque as "lead elbow is start to pull rearward"

So, my question on BHT is not about "what" but "how" does BHT create really good bat speed? explain that to me just like you explain to one of the blogger asked you about THT is happens in two phases. How does BHT really work?
