[O.B.Left]

There is a healthy amount of overlap in a sequenced release. You have to start rolling well before impact(at which point the left wrist is level). Since there is still an angle well less than 180 degs between the left forearm and shaft when the left wrist is level with any normal grip, and even less still at the point that the roll starts, you're rolling a big bat(the whole club), not a little one(the clubhead).

Makes sense to me: Sequenced, Simultaneous and all points in between being Overlapped to varying degrees. But re the latter : #2 fires prior to #3. Uncock then Roll.

"Delivery Line Uncocking Prep" then "Delivery Line Roll Prep" with special emphasis on the Roll . You can really feel them both and which one fires first. The Swingers Flail.... thank you Homer and Lynn Blake. Knowing your Trigger , your Throw is the answer to downswing black out.
