Robin,

Basically, with a small cap, you can charge it faster and more easily
than a large one, so it will be able to fire more times per half cycle.
This can happen with a static or a rotary gap.  Near the zero crossing
area of the waveform, some firings are simply skipped.  Thus the true
break rate of a 400 BPS rotary might actually be 300 BPS or so, and
will depend of electrode spacings, current and voltage capability of the
set up, etc.

No apologies necessary, they're good questions anyhow.
