One final point that I dont know the answer to.  I think that the tuned
length will be shorter for a 20B because the effective rate at which the
ports are opening  would be increased, much like increasing the engine RPM by
50%.  (and RPM has the most important effect on tuned length.)  If I am
guessing right, this would mean that a 20B's tuned length is 1/3 shorter for
a given engine RPM.

"the effective rate at which the ports are opening  would be increased"

Why???

I think you are off on this one Dave. Think of it as three one rotor engines
flying in formation :-)
