Can't always listen to the din of hecklers(via confident internal locus of control).

Mechanically i think we'd say that anytime the CoG was further from the hinge pivot than the support of hitchpoint on same load, the load has leverage over the hitchpoint from the benchmark of the pivot. But this is virtually always(if not load either balances or inverts on tearoff, CoG slightly further out than hitch point gives predictable soft fold down w/o inversion on tearoff). Then also as the support of hitch point approached the CoG there would be less leverage against line, but in distance it is pulled tighter perhaps he means this time?
.
i think part of the secret there is that the further out the hitch point is the more the rig can self tighten the line to floating limb(after tightened all you can and guessing line tension, let it set it's owqn to finish!). At the same angle of limb hinging down, rope is pulled tighter the further it is out. But the further it is out the more support can hang on even longer to pull rope even tighter. Is this what he means? Cuz actually support nearer CoG would reduce leveraging; be Zer0 @ CoG?
.
i think the lower, over the shoulder rope angle gives some support to load by pressing limb back into hinge, and thus needs less hinge. Logically if same rope is pulling away from hinge it separates faster, so in inverse look more hang time on hinge if pressing inwards to 'hinge pocket'. Hinge pocket pressure type support doesn't resist turn hardly at all compared to hinge support. But this leveraged pressure back towards climber is the new risk.
.
By having much support and then relieving some of it, by releasing some rope into system, so less steam pressure in the line and thus is triggered that way to folding by ground control. Then seeks path of least resistance downward, one side of downward is blocked, other side is open face as path of least resistnce calling limb to fold into. High tension rope near CoG, some hinge pocket pressure too makes limb action handle so lightly and deftly.
.
If sawyer has left batters box (bucket example etc.), and limb isn't folding as expected, can generally add more weight to trigger by throwlining out past hitchpoint on rigid part of load, seize 1 end of throwline down and pull other end to overload to trigger in lieu of sawyer out of batters box and not there to cut more hinge. Once again this takes less hinge than we are used to if have balance point and pressure back into 'hinge pocket'. Supports given from line tension are tension x cosine for upwards lift ,and tension x sine for 'hinge pocket' pressures theory.
.
Rope angle to hitchpoint is present in every rig. Even straight rope without angle(from support point to hitchpoint) should be looked at as having rope angle, but the dial is just simply set to Zer0. BUT this factor is a critical consideration, so pivotal as to always have a place in the formulae, even if only as a place holder for Zer0, should recognize for next time or if during movement rope angle changes (very likely). Should seek to sift out these critical points, and groom to what powers we need to extrude from them, while avoiding their pitfalls from the very start. 2 people can look like doing same job,but the one grooming fine points to maximum target at crit points should get at least 'cleaner movement' if not more successes out right. Of curse then the just say you have good luck!
Labor Under Controlled Knowledge.
work time.
edit:
ALSO, this rig hands off most of load to line, BEFORE tearoff. Does so more gradually, for less shock thru system and maintains better clearance.
Less shock to line and support point, as also converts from hinge as pivot point ; with rope as assisting support and folding around on 3rd class lever(pivot/control/load)
to
most of load on new pivot hitch point BEFORE tearoff
so that well ballasted 1st class lever(control/pivot/load) on rope is more lightly pushed around by hinge
(defining pivot of works as most loaded point?) and machinery to change when pivot changes
'Pivotal Change' as a game changer, when before tearoff and can use hinge/pocket to bulldog fairly well ballanced limb around on tight rope. Totally diferent game,feel, look, positiveness in the action/movement to me.
Less shock to line and support can be just icing on cake, secondary function to the light rigging ballet before hand.
