Dave,

I meant measurement of the maximum possible spark length.
If your sparks have the power to reach for example 60 inches, 
but are hitting objects
at 40", then I don't see how you can measure the maximum
spark lengths.  If this is the case, then I don't see how you
can gauge the relative performances of various secondaries,
TC's, etc.?   Sometimes the sparks can be directed in a certain
direction (where there are no nearby objects), and the max
spark lengths can be measured that way.
