You worked hard on that, but when I imagined Kev trying to get to impact with a zeroed out #3 angle on a TSP angle, I had to, delicately, suggest another view of things. I didnt enjoy doing it.

I dont want to sound like Batman talking to Mr Freeze but if only your debauched genius were put to some common good.

We're misunderstanding each other.

My post has been incubating for years. The illustrations took a few minutes. But they aren't Impact Illustrations. At Impact, even on the Turned Shoulder Plane, ideally the Left Wrist is Level. Therefore, there will be an angle between the left arm and clubshaft. It's reduced because of the necessity to reduce the #3 Accumulator Angle to use the Turned shoulder Plane, but it nonetheless exists.

But this post is about release motions and bending the Plane line. Both halves of the release motion should occur on the same plane line (delivery line) else the clubhead orbit becomes 3 dimensional.

Can the Flat Left Wrist be used with a Double Plane shift? I said no, that the wrist should be bent. But, you can have a Flat left wrist if you keep the clubshaft on the elbow plane during the downstroke AKA Sergio Garcia.

The Hogan Swivel is not the TGM swivel. I had always thought it was but I don't anymore. I do think that the Hogan swivel helped Hogan prevent Bending the Plane-Line. But it's not the only way.

Questions remain. What is the relationship between bending the left wrist and clubshaft plane?
