Ed; How much current depends on the point of the TC you are speaking of and
the size of the capacitance at that point.The NST is about 60+ma secondary.
The spark gap/capacitor is about 400 amps The secondary is in uA, but the
direct stringer current depends on the  "TOROID" capacitance. Your sumation
of current is correct in a average over all aspect, but not valid as an
instantanious peak current wiew. That is why current is said to be low/hi at
the same point. Average current is low, peak current is high and will kill.
