Well that pretty much settles it. Without a topload, distributed wins.
It is the question of current uniformity that matters. So our lumped 
LC frequency predicting recipes are just that - recipes and no more.
Therefore, Medhurst is not a gospel value for Cself of a bare coil,
just a useful recipe for predicting Fself.

     The next question then is: does secondary behaviour change from 
primary dwell to no primary dwell? I claim it does not after many 
many attempts to measure it. Anyone out there contradict that finding
(apart from C&C)? If so, please give the exact experimental setup and 
measuring techniques.
