In my opinion, the only reason to have extremely close spacing on the RSG
electrode gaps is to allow power control through the use of a variac. If the
gap spacing is large, then your RSG is only going to fire when your voltage
variac is turned all the way up. If power control is not important, then
space the gaps so that they fire reliably and that should be it.
