This scientific application stuff is tricky for a layman like me.

I think I remember Nyman explaining that the continuous looping of the whip that provides leverage to transfer momentum while conserving it could be mathmatically modelled as an infinite number of segments (?calculus is good for that?-I am not a math guy either,but most traditional scientific concepts/patterns should be "reducible" to math-another latman's assumption).The lead arm/wrist/bat/flail is similar to the "double pendulum action which COULD be thought of as a simple 2 segment whip.Certainly (?),momentum creation/transfer/conservation is the pirmary factor in producing a quick swing,because force application by muscles is too slow/prone to timing error.

Scientifically speaking the differentiation between ball on string type action and whip action is beyond my ability to fully understand,let alone explain,but these teo do seem to have essentials in commmon.

One nit I woulod pick with Dr. Yeager's description is that the absolute degre of separation is less essential than the dynamics/time course of separation/reversal.Too much separation means too long a swing with loss of quickness and increase in timing error.

I would say perhaps the primary/most essential perspective from which to view the swing may involve the consistent creation of optimum quickness of the coil/reversal referred to in golf(skilltechnologies) as "xfactor stretch".
