After chewin' on the math for two extremes in my favorite, performer, 2 coil
systems, I come to a Zchar. value between 3-6 ohms/gap.  It seems to agree
with yours pretty closely.  Dare we assume this is some sort of performance

Probably, it is more of safe range for someone wanting a quick and dirty
generalization that won't get them in trouble when designing and building an
important system which has got to work out of the chute.  Ideally, of
course, tweaking and dinkin' with the system after construction will improve
the performance. (perhaps by even adding or subtracting gaps!)
