.............................It must be noted that all leaders are invisible,
low current ionization paths.  The arcs move out along the multiply restarted
leader paths over time spans from 50 to 500 milliseconds for long arcs.  In
the
long time scale, late in full arc development, the leaders grow more from the
ends of the ever advancing arc channel that the terminal.
