Agreed.
I think John F. developed the empirical equation
L=1.7×SQRT(P) on basis of fixed BPS rate (120 BPS)
given input wallplug power.For class of the coils he
considered.
IIRC,he has said once that factor 1.7 should have be
changed to aproximately 2 for power given in form
P=E×BPS .E stands for the energy stored in a primary
capacitor.
Not sure about that though.You should ask him
directly.
