Hi Bill....

basically ......  a small transformer with a cap larger than the resonate
value of the transformer uses
120bps ( NST with .01mF)  a large transformer ( piggie) with a smaller than
resonate sized cap can go to
240 bps. A magnifier system can use 480 bps.  but for best results and
longer sparks, 120 bps is the
optimum setting. this allows for a full charge ( current and voltage) to
build up in the cap befor it is
discharged to the tank circuit.   (( 120 bps is set for the peaks +/- of
the AC waveform)) any additional
bps not at 90  (+/- 1-2 degrees) will result in partially charged caps at
the dischage ( gap closure)
therefore not giving you the fullest amount of power to the tank circuit.
