Malcolm -

What transfer efficiency are you referring to?
What is an energy trade?

The overall efficiency I am referring to is the

    OA Eff = energy out/energy in

The "energy out" is the spark energy. The "energy in" is the energy going
into the NST.

How do you find these two energies for your TCs? Any examples from your
coils?

John, below you distinctly say:

I've cut the various headers out for brevity.

I know you are particularly interested in matters of efficiency. It
is not difficult to calculate transfer efficiency and I won't repeat
the procedure since it must appear any number of times in the
archives. Since you can know the primary energy when the secondary is
empty, you can do it for any number of energy trades and sum the
partial results to find an overall figure for a particular bang (and
whatever spark it might produce.

However, you do say something about sparklength also and I am simply
pointing out that when you do talk about sparklength, you cannot
ignore parameters other than energy shot size (and BPS if relevant).
