My hardware can go up counting to 4096 bangs but actually 32 were well
enough to exploit all what I could from my maximum available bang
energy.

Indeed.

I wouldn't say so. As I commented in my web page, Fig.5 "nice" maximum
is due to measurement uncertainty and to be taken with a better
confidence as a saturated maximum. I mean, I believe readings -at- 300, 350
and 375 Hz for 10.7J are actually the same. Read it as "no improvement
above 300 Hz".

I don't know... For 120 BPS I would need to remove pairs of electrodes
from the RSG, as just lowering its rotational rate (which I can do at a
glance) results in a premature discharge of the charging primary
capacitor. But what about the rotor balancing? That's a Bill Wysock RSG.

This test could be easily done by an SSTC owner with drive possibility
from a programmable function generator.
