Couple of questions for clarification :

1-Are you saying the above will happen given an attempt to thrust along the eye line to the ball? The eye line to the ball being steeper than the plane angle.

2-Dont understand how in your geometry the hands would be moving "up" and uncocking the left wrist which makes me think I've lost you somewhere.

OB,
To limit the discussion I've picked out the above two questions. Could always cover the others in future posts if you want to re-ask or pursue them. However, the above two questions I percieve to be most on topic.

1-Are you saying the above will happen given an attempt to thrust along the eye line to the ball? The eye line to the ball being steeper than the plane angle.

Yes that's basically it. However, let me clarify. Again, just to keep this simple we're using a single plane downswing. The fact that your head and eyes are above the swing plane looking towards the ball - and you naturally thrust- i.e. move towards where your eyes are looking - that is getting your hands to cover the ball visually i.e. eventually get between your eyes and the target. It seems counter intuitive to make an on-plane motion i.e. hands & clubshaft headed to the ball by visually directing them somewhere else than the ball - but that is what you need to do from your vantage point above the plane.

Clarification: The hands don't thrust down the eye line but since they start flatter than that - in this aiming point concept they'll have a tendency to eventually end up on the eye-line - then the hands will move above the original single plane downswing.

Based on various factors I'm not saying that the hands will end up between the eyes and the ball however they'll have a tendency to move towards that - steepening the plane - if you are thrusting towards the ball. By steepening the plane - I mean the clubshaft plane at impact. Becuase the hands move above the original single plane that we started with - the hands actually moved flatter - ended up above the original single plane - requiring the shaft to be steeper in order to hit the ball - which the uncocking allowed to happen.

Here's one example of what I would use as an experiment to see this for yourself. Sit in your desk chair at the house and lean the grip end of a club on the armrest and have the clubhead on the floor ahead of your feet - basically representing a plane angle. Note where the plane line would be, the ball etc., now take your hands down that shaft angle, having the hands move in front of your body like a real swing and see if you feel as if they are moving towards a point inside the plane line. Now do the other option - thrust them at a point on the plane line and see when they get to impact if they are slightly above the plane.

This falls under the category and you have to understand what perspective you are analyzing movement - on the one hand the hands are coming right down the plane towards the plane line from a 3rd person perspective, however with that same movement - from the 1st person perspective - you can't be trying to move them towards the plane line given your perspective. What's happening and what you are trying to do to make that happen are TWO COMPLETELY DIFFERENT THINGS. That's an important principle that the golf industry and probably the scientific movement industry has not yet understood.

2-Dont understand how in your geometry the hands would be moving "up" and uncocking the left wrist which makes me think I've lost you somewhere.
Good question for clarificaton - what I meant was compared to the original single plane - that is the hand position at the top - through to the ball/plane line - when using the aiming point on the plane line as discussed above. The hands would tend to be higher at impact than the original plane - so you could say that the hands would move flatter from the top - creating higher hands at impact - and therefore to hit the ball - a steeper shaft - allowed by uncocking the wrist more. You make a good point - the hands don't move up - just less down and higher than the original single plane that we are using in our theoretical example to understand the concept. Therefore I was saying that you'd be more uncocked just in order for the clubhead to hit the ball than the original single plane.

Appreciate the questions - allowed me to learn a few things myself and completely understand why you would be asking those as it wasn't clearly explained in my original outline. Check it out for yourself and look forward to your feedback.
