Pure in a dictionary sense means free from..., or unmixed with any other matter. Mike, I think I understand where you are trying to go, but am not sure we can get there. Are you looking for why Hinge Action was moved to Zone 2 (Power, Arms, Force), being a by-product of strictly an Angular Motion?
True Hitting, as I think you are looking for, would mean per 2-M-3, Power Package Thrust
alone, forfeiting Momentum Transfer. Also, per 6-B-3-0,
True "Drive Out" (yes, I know that it was changed to Throw Out in the 7th edition; a mistake IMHO) Action holds the clubface in Impact Fix alignmnet and automatically produces Angled Hinging.
"True Hitter" is also referenced in 7-2 regarding Clubface Alignments.
