I think that you have (almost) hit the nail on the head. The zoom DOES come
from dive speed, but it is the angle of the dive that most flyers get wrong.
I learnt a lot watching Nic Wright when he toured Australia a few years ago.
He would build up enormous tension on the line (either by a conventional
launch or by circle tow) and then would perform a brief shallow dive (1.5
seconds@20 degrees?) to convert the tension to speed and then ping.
There are too many flyers in Australia who love to try and wrap the
parachute around their tailplanes in ridiculously steep pre-ping dives. It
is just not necessary.

Oh, I fully realize what you were talking about - I was disagreeing with the
statement that you need to dive excessively. What's the point in bleeding
off altitude for airspeed? That isn't what a zoom is about. Sure you need a
mild dive to perform this, but you don't need a steep one. The added effect
from the zoom is gained mainly from tensioning the line...not from dive
speed. That's why the wings need to be that strong on zoomable airplanes,
the winch is almost pulling directly downwards with up to 200lb of line
tension.
