[TCML] Charging a cap to 63% V

The reason why I ask this is that I want to get as much out of my nts's as 
possible. With them just sitting there shorting the output they pull around 
18.5 amps @ 120v. When connected to the TC, which has around a 64nf tank cap 
and run it , it also pulls around 18.5 amp @120v. So can I assume I am maxed 
out on the capabilities of the nts's as far as getting the most out of them 
? T map says the ideal for a rotary is 161nf but wow I don't think I can get 
anymore out of my nts's. I know that in the real world they cannot output 
210ma @ 9000v  and I think T map does . Am I correct on this. If so in 
reality what could I estimate the output of the nts's to be, maybe 210ma @ 
4500v. Does Tmap take 8.33ms ,210ma and V (9000) and come up with the cap 
size ?
