Richard,

For an ideal transform, 6.4nf will be resonant (all of transformer impedance
is inductive reactance).  With winding resistance considered, the inductive
reactance will account for a smaller portion of the total transformer
impedance.  Calculated L will be slightly smaller and resulting resonant
capacitance will be slightly larger.  So, 6.8 nf may be close.  In any case,
I would shoot for 1.6 * Cres for an LTR value and make sure your safety gaps
are properly set.
