Not really.

HV Engineering (text by naidu & Kamaraju) clearly explains that spark 
distance, ie, potential is totally independent of the waveform.

Yes, if you run a coil in 120 or 500 pps mode, certainly the spark does grow 
to long lengths.

I run the coil using a very high resistance, on DC charging the cap, so it 
fires once every 120 seconds.  A 6 ft long spark shrinks to approx 18 
inches.  It does not have time to "grow" to long lengths.

In this mode the 1/2 inch rod gap measurements, as I posted, are very 
accurate, usually within 2-3%.

I made accurate verification measurements using Terry Fritz's antenna system 
hooked to our TEK storage scope.  Also verified with the standard equation 
assuming approx 75-80% efficiency.  This data was posted in the archives 
years ago.

This rod-gap system can be used by anyone who wishes to confirm their coil's 
actual output.
