well, let me tell you: if you read Tesla's deposition when he was 
being sued by the Marconi corporation, Tesla clearly states that for 
"power transmission" he would run his coil in undamped wave mode, 
without streamers! he states in no uncertain terms that streamers 
where wasting energy. He only put out streamers when he wanted to 
impress members of the press. So, in a way, your calculations are 
correct. I'ts not that tesla ran the coil without toroid, he just 
didn't let sparks out.

PS.: by the way, are those figures calculated by software, or actual 
measurements? the figures could be the result of incorrect modeling 
of the software, like if it was treating the circuit as a lumped 
element circuit, instead of a resonant one.

hello dave, working professional, aka dwp :-D
"CURRENT PEAK AT BASE !" - oh yeah, maybe you`ll show me that peak in
my coil:

PLEASE! :-D
for comparison - a coil without a toroid (but who works without one?):
