As I am sure you are aware, measuring static Q is nearly meaningless with
regard to dynamic operating Q factor.  John Couture's method of measuring
dynamic Q by measuring the bandwidth factor is the very best way to do it
--- and the calculations of Vpri x dynamic Q produce a valid output of
actual Tesla coil potential.  John's method is detailed in his book and is
must reading for anyone who really wants to know exactly what their coil is
producing in terms of potential.
