The above is true for resistive ballasting, but for reactive ballasting,
it is true only when the spark gap is firing.  When the caps are
charging, a reactive ballast actually can increase the current flow,
due to resonant charging, in which the inductive reactance of the 
ballast "neutralizes" the capacitive reactance of the caps and 
current flow is limited only by wire resistance, etc.  Many coilers
prefer not to use resistive ballasting exclusively because of the
amount of power that is wasted in the ballast.
