Ed,
You are correct about the long time to grow. I noted this before on
this
list. I have timed some long streamers of 10.5 feet off of maggey #11-E
using video frame counting. (1/30 sec) From the beginning of break out
from
a location on the torid to max strike distance and max brightness in
strike,
I have counted as many as 10 frames! 333 milliseconds! that is about
200
pops of the rotary and 5 orders of magnitude longer than the period of
the
electromagnetic wave of the resonator. Again, I say the air has to be
pumped up and an ionizing path burned out. The large toroids and lower
base
impedanaces of the system can supply a lot of energy which can help the
spark tunnel out a little farther, but it takes time.
