Jack,

You have introduced the terms THT and BHT to describe "the most active hand at each point of the swing". You also note "in a good swing, pressure sensor pads on the bat handle indicate the hands are exerting a fairly even force".

I have studied these statements, and can reach only one conclusion: Your most active hand is merely that which APPEARS most active FROM AN OVERHEAD SHOT (italics intended).

Since the CHP is in a plane which is not perpendicular to the camera sight line, the hand which appears more active is always closer to the camera. Initially, top hand (higher) appears to circle around bottom hand. Finally, near contact, bottom hand (higher) appears to circle around top hand.

THT and BHT are visual cues to relate bodily action in an overhead shot perspective. They indicate nothing of hand force dominance - merely that hands are always in a push/pull relationship.

Is this observation correct?

Thanks,
Mike.
