This observation would agree with the data from 'Gaseous Conductors',
where the author noted that the current *density* in an arc remains
relatively constant as the gap current is varied.  This would mean 
that if the gap current were doubled, then the arc cross-section
would roughly double, cutting the resistance by half.

That seems right to me, insofar as SQRT(L/C) should be raised until
it is about 30 times Rgap (point of diminishing return IMO).
