After studying Grunde's video of Mathias
Lilleheim's "supersonic" backcast, my thoughts are
these:
#
He's using a full flex rod.
#
Unloading occurs (apparently) just prior to RSP (rod straight position) as
acceleration ceased.
#
Following RSP and the start of loop formation, the rod tip goes into great
counterflex so that the tip almost touches the floor !
#
Rebound is commensurate with the counterflex, so it is
extreme.
Without seeing a great deal more of the line, I
can't be sure. I think, however, that the trajectory of "up and back"
was established prior to counterflex. Counterflex temporarily pulled
the rod leg of the loop down. This began to rise a bit with rebound,
but then continued to rise as the momentum of the traveling loop pulled the
counterflexion deformity of the rod leg back up in the direction of the
trajectory. (What Paul Arden calls, "sucking it
up".)
This is in keeping with the dictum: What
happens prior to RSP affects the fly
leg of the loop. What happens after
RSP affects the rod leg of the
loop.
NEAT STUFF !!!!!!

Let's see how some of you including Walter
Simberski look at this apparent defiance of gravity. Do you think
that "lift" is responsible for this amount of levitation
? G.
