There are 3 factors in this discussion:-

1. Left wrist condition
a) Mechanically flat left wrist / geometrically flat left wrist
b) Bent left wrist

2. Sweetspot Plane line alignment
a) square to target (10-5-A)
b) out to right field (10-5-E)

3. Clubface alignment with respect to face of plane
a) Fully turned to face of plane (ie. no "squaring" or roll of clubface prior to uncocking)
b) clubface rolls off face of plane prior to uncocking

All of these criteria have been specified since my first post.

It strikes me that 1(a) + 2(a) + 3(a) = impossible

1(a) and 2(a) require the clubface to roll off the face of the plane 3(b)

2(a) and 3(a) require a bent left wrist 1(b)

1(a) and 3(a) require a plane line out to right field 2(b)

So in Jeffs Photos I would say that they are off the square plane line (maybe heading back towards it at this point of backswing) ...but photos and parallax prove nothing...just lead to debate... the answers to this question lies in principles...I think...I am slightly confused but sure that the answers are nearby!

what a sweet spot roll off the plane? ...

Edit: ok.. Are you trying to say sequential and overlapping release of accumulator?.. Standard vs single wrist action.
