This has me thinking, if I understand this correctly, there is no power to be gained from the second pivot? It just happens to allow my body to rotate around?
heh... dude... this is going to be such an abstract concept that it's probably almost a waste of time for me to write it hehe.
in a low-snap throw (usually with a rushed shoulder) the second pivot occurs merely because the body keeps moving after the release.
in a high-snap throw (with acceleration and force transferred to the disc) the second pivot happens if you get your full body into the force transfer.
basically, you have to separate the throw into a push and a pull. you push the disc into the power zone (aka point of impact). you pull the disc through beyond the point of impact. the second pivot has nothing to do with the push... nothing at all. if you try to milk a pivot into the push you are getting nothing from it, you'll only ruin your body positions and probably wear out your glut on your pivot leg.
if you give a hard "pull" at/beyond the point of impact, you will pivot if your entire body is into that motion. you don't force the pivot, it happens because your entire body is opening up and it will force the pivot.
most people never reach the point of impact. low snap throwers release around 1' early before ever reaching it.
even for a high snap thrower, if they don't have a second pivot in conjunction with the pull portion it means they aren't harnessing their entire body into the throw.
a good example of the second pivot.
pre-pivot (look how far forward the disc is already):
immediately after release the pivot has started:
the pivot continues into the follow through:
