Yes, that is what I've been saying for years now. The transformers 
current is everything as far as how fast it will get there. Even in 
instances of short duration super high charging, it is still the current 
making it possible. The physics for cap charge are well known and they 
are absolutely correct, but transformers will differ a little from one 
to the next (even NST's) and then there are situations like 
ferro-resonance discussed. So, many high current variables fall into our 
coil operation and change power throughput and therefore power dependent 
spark length equations. Losses anywhere affect performance including the 
transformer (good or bad), although the gap is still #1 for losses.

Maybe. But until I see the specs and analyze what is different, it is an 
unknown and unconfirmed until a second body recreates it. One thing I do 
know about small coils is their tuning is very sensitive. The 
sensitivity (Lpri) due to low turns and actual winding length is part of 
the main problem I dislike. I've always liked larger coils simply for 
this reason.

Take care,
Bart
