I'm not sure about a few things.
Brian says alpha, defined as on plane torque, is handle rotation according to Enso...but I'm guessing it's only handle rotation around impact area...alpha at start down wouldn't have much handle rotation right?

When Brian says 80% of clubhead speed is attributable to alpha, I'm thinking this is more of a math thing...meaning if you have a equation set up where club head speed can only be attributable to 3 factors or torques - alpha (on plane), beta (off plane), game (around the shaft) - then mathematically it turns out that 80% of clubhead speed comes from alpha. What do you make of this interpretation?

What are you asking? If ball was at chest or shoulder height and you hit it from a normal top of backswing...would alpha still be responsible for 80%. I'd say yes, and probably more so. I'd want a split grip to accentuate.

If you are just asking how to get max clubhead speed, it just makes sense that what is being asked about is ON PLANE motion. Can you handle drag to 120mph? doubtful. can you use split grip idea and have a push and a pull about a point of rotation between the hands and speed up the clubhead past the hands...very likely.

Also I don't think it's "just mathematics" resolving the components... if you have alpha=0 and beta=0 and tried twisting the clubface close you'd be lucky to get 10 yards. Similarly for alpha=0 and gamma=0 and doing an offplane motion, what could one do ...15 yards? and you'd have to have a might open/closed face to boot.
