Hi Jim,

The 1.5*Cres (really 1.57*) is for static gaps (set properly) to give 
about 120 BPS.  The LTR value also helps control the resonant rise, 
but a properly set safety gap should be considered mandatory.  It is 
still possible to get too high of voltage with this LTR cap if the 
main and safety gaps are set too far apart.
