has i ever said that my values are for the case with a streamers
present? not at all.

calculated by software, which is based on the measuring results of
many real coils :

impossible. read this first:

"Examples of voltage and current distribution profiles for Tesla
secondary coils.

Example 8: Typical coil with toroid

The transimpedance is 43K ohms, much higher than the 29K predicted by
a cosine current profile, and almost equal to the _uniform current_
value of 45K ohms."

:-D

btw - here are charts for my coil:

i think that "peaks" are present only at inefficient coil, with a
funny small toroid, or even without one :-)))
