Anyone who has ever scoped the secondary activity on a disruptive coil
can see that all activity is over long, long, long before the start of
the next bang.  With the inherent losses in any secondary system, this
just is the way it is.  Even if the BPS could have been increased to
start a bang before the previous one died, I don't believe that the
technology existed in Tesla's era to time spark gap firings with the
phase of a ringdown.

   Surprisingly enough Marconi did just that by around 1907 with his 
"timed spark discharger", an ingenius rotary spark gap which actually 
had one break per cycle of the RF, which was of the order of 20 kHz.
There are pretty detailed descriptions in some of the early books on 
"wireless" and you might even find something on the internet.  As far 
as I can see this would have produced a continuous wave but not sure 
how noisy it would have been.  Probably as clean as an arc and much, 
much cleaner than the regular spark system.  This was several years 
after Wardenclyffe but certainly in Tesla's time.
