I think once one goes down that path, it is then simply a question of
how many gaps/pipe sections work best for a particular coil. My
preference for a comparison is to ensure firing voltage is the same
for whatever gap types are being compared. That means _monitoring_
the firing voltage, not relying on some variac setting which is
obviously subject to resonant charging. This enables the meaningful
inclusion of any type of gap in such tests.
