Basic Motion does not use "Wrist Motion". We don't Cock the Left Wrist during Basic Motion. We use "Hand Motion" to Turn and Roll.
Hinging is Clubface "Motion Alignment" through the Impact Interval. It's the difference in Clubface orientation from "Impact" to "Separation". Layback Only, Close and Layback, Close Only.
Since there is no longer a Hinge at the Left Shoulder (zero #3 Acc.), Clubface Motion through Impact mirrors our "Hand Motion".
Thus - "Hand Motion - Hinging"
"Hand Motion", All Clubface Motion Alignment will be like "Angled Hinging". Accumulator #3 is needed for Horizontal and Vertical Hinging.
