That chart (and how you go about doing it) is the combination between 3 
factors:
1) enough caps in a string to hold off the voltage.. 10 for a 15kV NST
2) enough caps to get the capacitance where you want it (that's why 
there's 19 0.1 uF caps for a 15/30.. it's to get the capacitance down 
low enough.
3) enough caps/strings in parallel to handle the current
