Luke,

I may read you wrong, but it looks to me like you overlook the fact that 
the current is not determined by the value of the gap resistance, but by 
the combination of cap voltage and size, and inductance of the primary 
coil. The resistance in the gap is in the 1-5 ohm range, the surge 
impedance of a primary is in the 100s of ohms.

Ipri = U*sqrt(Cpr/Lpri).

Cheers, Finn Hammer
