Unless one uses a sync RSG, it will be difficult for most users to
observe the 120BPS limit.  As the cap size simulations on my web page show,
most static gap configurations will result in multiple bangs per mains
half cycle, greatly exceeding the 120BPS mark.  For a 15KV/60mA NST with
a 20KV static gap, one would need about 15nF, or three of the EMMC's, for
the cap to limit the BPS to near 120.  Still a bargain compared to rolled
poly or commercial caps though.
