What exactly do you mean higher compression? Air is an insulator which resists the spark jumping the gap. People running superchargers or turbochargers run smaller plug gaps, as low as 0.015". High compression, superchargers and turbochargers cram more air molecules into the plug gap which inhibits spark travel. It is like those hi tension power transmission lines are suspended on high towers with the wires held far apart to keep the 118,000 volts in the wire.
118k volts, try 230 k or more, there are lines in places that are running close to 1 mill volts. Are those lines relying on high amps to do the work? I don't think so, the higher the voltage the less line loss there is over long distances.
