hi, Chris here....

I'd say stop trying to calculate and get a scope, None of the calcualions for
my coils have ever been right.  The calculated frequency of my coil was
supposed to be about 900Khz, but in fact it was 200Khz.  Thats 36" coil,
2.75" form, 0.315mm wire.

Humm, Not really helping am I !
