PS I would only measure to the top of the loop... not counting the
'fold over' that makes up the loop. The wire actually folds back down
the main radiator and thus cancels its lenghting effect (except for
the small capacitance I talked about).

Isn't this somewhat similar to linear loading... which does lower the
resonant frequency?
