Keep in mind that pulses/sec is not breaks/sec, at least as defined by
the cap mfr. A TC typically runs at almost 90% reversal, which is a lot
harder on the cap internals than the 20% or 50% often spec'd in the
capacitor data sheet in connection with the life spec.
OTOH, reducing the voltage across the cap by a factor of two has a HUGE
effect on life.
