@Agerasia I think that your maths is in error as Hertz used to be cycles-per-SECOND in old money. In any case testing these plugs in the open air (1 bar pressure) is IMHO meaningless. The reason being that much more voltage is needed to fire the plug when it is under 150 to 180 pounds per square inch of pressure. The Champion Spark Plug company used to make plug testers that had a glass jar surrounding the plug. This could be pressurised to 100 psi or more for a proper test.
no one ever shows these sparks under high pressures to see how they really form

Hi,
That's 10,000 hz isn't it :)
Remember each plug only fires once per 4 strokes, so 2,500hz is a true representation of 10,000RPM.
