Actually it is.  Elsewhere I stated that I would uput a static gap 
across the rotary to catch misses. I would definitely want to 
resonantly charge Cp although I'd expect the value of Cp to be chosen 
according to breakrate. I guess my main point is: if the zero current 
crossing spikes in the gap are the real nemesis for NSTs and these 
are adequately filtered, all should now be well, shouldn't it?
