Doesn't count - Ksys is determined by the proportion of *total* 
inductance on the secondary side falling within the influence of the 
primary. "Total" means secondary coil+extra coil.  They are really 
two parts of a single structure. Bear in mind that the pri-sec driver is 
not a voltage source so you cannot treat the resonator as a separate 
base-fed entity.

Tesla never switched his coil on for prolonged runs. In his words 
"half second closures of the switch". I understand what you are 
sying. Nevertheless, you will find that in practice the only thing that 
allows the gap to quench properly is strong streamer emission from 
the secondary/resonator system. If you don't believe me, try 
interrupting the current in a primary with no secondary breakout.

3) Tuning the secondary coil to the 1/8 wave (less voltage, but a lot

The pri-sec driver is not a voltage source.

 4) Tertiary is not bogged down at all by the flux from the Lp and Ls

Neither is the resonator in a two coil system.

5)Tertiary is responcible for all the VSWR, not the secondary

If you mean voltage step-up, that is clearly not true. There is a step 
up commensurate with the SQRT(Ls/Lp) ratio in the driver.

 Why would Tesla even bother building and operating these coils if he

Which he never did. I'm afraid that I am forced to concur with the 
results I am seeing from modern instrumentation not to mention 
some fairly searching experiments.. Do you think Tesla was correct 
when he tried to relate all his tuning to the length of wire in his coils?

 As far as the 22 mega volt RQ coil, those are his claims, I am just

Of course. A number actually. It is very very easy to put a magnifier 
together. Predictably too.  As regards voltage, consider that no coil 
can withstand more than a voltage allowed by its length. It is a simple 
surface tracking issue. You can reach the limiting voltage for a 
given resonator just as easily in a two coil as you can in a magnifier.
Bear in mind that in a magnifier, voltage step up is shared between 
two coils so obviously a given resonator will have extra voltage added 
to it by its "secondary" portion of winding in a magnifier if the 
amount of primary energy is increased beyond what it was run at in 
a two coil system.
