Tesla Magnifying Transmitter: ratio between secondary and extra coils

Regarding the Tesla Magnifying Transmitter. Does anyone know if there is any math or reasoning regarding the ratio between the diameter of the secondary and extra coils? The Colorado Springs TMT had a ratio of approximately 6 to 1 and this currently appears to be the standard ratio being used. However, I have seen a Eric Dollard's Extra Coil Calculation document in which the extra coil diameter is 40% of the secondary coil. I get the impression that there is some form of magnetic coupling or impedance matching behind the diameter of the coils. If someone could explain the reasoning or post the latest version of Eric's extra coil calculations that would be appreciated.
