Hi Winston, all, 

I don't think this SRSG coil skips any firings at 120 bps.  I've never
seen that happen on the scope.  Also, since this coil tends to
resonantly build up, if it misses a firing, this should cause
the safety gap to fire, but it didn't.  Also, if it skips a firing, the
next stronger firing should cause breakout.  I didn't hear any
unsteadiness of the gap firing.  I don't think my line
voltage is changing much, but I guess it could be.  Regarding
your coil, static gaps can do some strange things. 
Also, some ionization can survive at 60 BPS, especially indoors
as I'm operating.  It still seems to me that if the breakout voltage
was dropping to near zero during subsequent streamers, as Dave
suggested, then my coil would be unlikely to stop firing.  Or 
maybe I misunderstood what Dave meant?  It would seem to
me that the breakout voltage may be rather high even for
subsequent bangs of a TC, despite residual ionization and/or
heating of previous streamer paths.  I could be wrong though,
because there are still TC mysteries.
