I think you're referring to something I said. Certainly if the charging
current is high enough, you could have multiple (even dozens) of firings per
presentation. I think most tank caps would fry under such conditions with
such high current transfer.

I didn't intend to say that RSG's are intrinsicly a 'one firing per
presentation' gap system, only that its better suited to it under the right
conditions, as you said, an LTR cap with SRSG. Certainly the firing pattern
of ARSGs and static gaps are nearly chaotic in practice. I really recommend
Richie Burnett's website, he's got real scope shots that indicate exactly
what goes on (and I'm not quite crazy enough to try direct connection scope
measurements like he did), so I'll have to take his word for it. And it
seems most of his results support the various computer simulations others
have done.
