This is similar to what I have observed in coils running at the 
higher frequencies, as the frequency goes up it seems there is less 
tendence for the sparks to fork and the discharge looks more and more 
like a luminous discharge. I also notice that the spark length seems 
to decrease at the higher frequencies even when the voltage appears 
to be the same.
