Although efficiency and spark length
may go up as you take bps down to 120bps,
the way TC arcs are formed may (or may not) come into this.

When the tank capacitor is charged, the spark gap is
bridged, and the capacitor resonates with the primary,
and transfers some energy to the secondary, which begins
resonating and comes out with a high voltage pulse at the toroid,
which may be millions of volts depending on
the system. This voltage only has the capability to 'jump' across
about twelve inches. The (ten-foot) arcs produced by tesla coils are
only produced because after one 'resonation,' the toroid makes a spark
about twelve inches long, and then the spark dies, but the next 'resonation'
and the next spark comes so close after the first one that the 'channel'
of ionised air is still in place, and the second spark travels down this
'channel'
and then jumps another 12 inches, and so on, out to perhaps ten feet.

I saw this demonstrated by Malcolm Watts, when I went down to see him awhile
ago. He has this gadget, with a flyback transformer and a small ordinary
transformer,
that he powers the tank circuit with, and the coil will run at ONE bang per
second.
this goes 'click' 'click' etc, and the spark coming off the toroid to a
grounded object
is only twelve inches long because the plasma channel has long since gone.
(This
coil is capable of 5+ feet arcs normally.)

I'm not sure about what BPS number at which this would start to have effect,
limiting
spark length though.
