Hi Terry:

I'm curious as to the derivation of the pi/2 factor.  As far as diminishing 
NST resonant rise, the further from a mains-resonant value (i.e. higher), 
the better.  And a lower cap value would charge to a higher voltage, so 
that argues for a lower value.  But the inductive kick effect favors the 
higher values.  Who knows what happens when the current limiting shunts 
saturate.
