You are correct, anyone who gets multiple firings per ac half cycle
using a static gap will not be firing at the peaks, but many folks run
their coils this way. Some folks claim that high break rates are better
than low breaks, but I don't agree. I prefer low break rates for the
ultimate overall performance.

If the firing skips a beat, the break-rate will not go up... did I imply that
before? If so, I didn't mean to imply it. In any case, static gaps often
don't really run at 120 bps, but tend to fire at a variable and erratic bps.
