Does this mean that I am "prudent" now? :)
DC motive power with a variable RSG has been my mode of operation
since 1990.  There are so many interesting dynamics to the arc as
the BPS is moved around and through this "critical value" that I
consider a polyphase/DC/variable RSG architecture essential to 
enjoying a coil to its fullest!!  The BPS knob is _mandatory_, as
there is fun stuff above as well as below the "critical value".

I have also found that this BPS "critical value" depends 
considerably upon the physical scale of the coil, perhaps due 
to the squared/cubed law at work on the lifetimes in the ion cloud.
Finally, an effect that encourages increasing the scale of a coil!!
