Homer listed delayed hip action for the swingers basic pattern in the 4th 5th 6th and 7th editions, Homer layed out the basic patterns as a starting point, a recommended example, there must be a reason why delayed hip action was chosen over standard. My opinion is that because delayed is lead by the shoulders in the backstroke this variation would tend to prevent overswinging as he says vs. A swing that is lead by the hips is probably more conducive to a maximum swing radius. When looking at the rest of the components for the swingers basic pattern at least in the 5th edition he uses flat left foot action and right anchor, two components that will limit the range of motion vs. Standard foot action and standard knee action which would or could produce maximum swing radius. So as you mince your way through G.O.L.F. You may be able to lengthen the swing but it is first recommended to use a swing with emphasis on a shorter swing radius, a more anchored swing.

I think you are sniffing it....HOWEVER....some of the precision in this analysis is lost in the PLANE ANGLE and procedure type..."length" is a nebulous concept in my mind....TSP hands go HIGH and less DEEP...Elbow plane hands go DEEP and less high....I depending on the amount the power package is "lifted"...you COULD HAVE a really "long" swing with high hands and MAJOR hip turn in some ways allowed by standard knee action...or you could have a "short" swing with major hip turn ala Ken Venturi...one component Homer didn't make complete allowances for (other than axis tilt) is deviations in the flexibility of the spine...
