pp#2 in hitting procedure

[phimaynard]

Per 12-1-0 N°4= triple barrel (1/2/3) (power accumulator N°2)
per 12/1/0 N°6= Turned shoulder plane (any plane angle shift is very hazardous)
per 12/1/0 N° 7= Zero plane angle variation(without any variation, that is no shift)
per 12-1-0 N°10= Hinge action angled:" hold the Flat Left Wrist vertical to the Inclined plane"

per 6-B-2_0 : Power accumulator N° 2 When the left wrist is cocked (in excess of the selected Clubshaft-Left Hand Angle in the Adress or Fix positions) it forms the second Power Accumulator.

My question is : When PA #2 is applied during this pattern?
How can I in the same time hold my left wrist vertical to the inclined plane, cock my left wrist , keep a shoulder turned plane ,and per 12/1/0/7 no plane angle variation, that is No shift
Thank you for your help
