The ability to "stretch" a streamer depends on the current in the streamer.
Large currents allow more streamer length after the initial strike.  Similar
to climbing arcs with 60 Hz transformers.

With your tuning efforts you apparently have increased the available
current.

Also, be sure to experiment with elevating the sec coil.  This fine tuning
of the coefficient of coupling factor will insure the longest sparks and the
best load-energy transfer this protecting your caps and xmfr.  Even small
amounts of gain will reduce the strain on your caps.
