It sounds like you used the same cap with both gaps.  I can't say how
your bang voltage differed between the static and SRSG gaps, but if it's
similar, I would not expect to see a difference in performance between
the two.  It's only because I was able to use a larger Cp with the SRSG
that the bang size (.5*C*V**2), and hence performance increased.
