Electronic Conversion Kit

Shouldn't the coil primary resistance be taken into consideration when selecting a ballast resistor?

Here's a question I asked Rick Ehrenberg about the conversion kit I bought from him...

"Would it be a safe assumption that the resistor value plus the primary resistance value would be about 2.0 to 2.5 ohms allowing a mix and match of coils and resistors adding up to that....Or am I way off base?"

His answer was.........

"Your math is absolutely correct!
Rick"

Sorry, one more thing to think about.....Maybe time to switch to an HEI system :)
What I'm saying is, I'd rather be off with "too much" ballast, than "not enough". In other words, I'd rather be safe than sorry. Because sorry will happen at the least opportune time.
