Below Plane Stretch of Extensor Action

[FL-John]

Homer mentioned in the book that the strech of Extensor Action is below plane, except for zero #3 Accumulator. My question is twofold:

(1) With zero #3 Accumulator, is the stretch going backwards along the face of the inclined plane?

(2) If there is #3 Accumulator, AND with the left arm at address, being off (and usually above) plane, how much is BELOWplane. I mean, is ithe feel of streching slightly below the plane anlge??

The reason I ask #2 is at times, as I try and utilize the below plane strech of extensor action, I think I inadvertently roll/swivel my entire left arm in an 'over the top' of my right forearm type of move.....it gets the shaft too flat going back!

Thx

John/Lynn - re: 'below plane' action of extensor action - yes if the plane you are relating to is 'the' plane, the sweetspot, the 'plane of force'

However in relation to the path of PP1, the plane of PP1, the plane that the hands travel throughout the stroke - that extensor action is ON said plane IMO. The plane on which PP1 travels is 'inside' the sweetspot plane, and thus the 'on plane' extensor action of the hands is below the sweetspot plane. Does this perspective agree with your views of below plane extensor action?
