1. Can anyone show me where, in the book, the terminology 'start up swivel' is used???

If not, then please, lets not use it. Of course, it may be used, hence, my request for a reference.

2. By swinger, lets define.

True swinger - centrifugal force rules, including the squaring of the clubface.

'Swinger' - utilizes centrifugal force for power (loading, etc) but not necessarily alignment of the clubface, and in this case, adjustments may need to be made.

And again, start up swivel please.....

Did a search and could not find 'Start up Swivel' As far as "adjustments may need to be made" are you refering to 2-F. "When in doubt, “Turn” the Clubface so both the Clubshaft and the Sweet Spot will be on the same Plane at the Start Down. Both Planes always pass through the Lag Pressure Point"?
