this idea is bad independently from the leakage inductance value,
coz by such way we obtain  the answer only in a specific situation -
at the specific conditions. but i`m offering to get something  more
common, because the leakage inductance is the property of the given
variac and by  knowing this value we can calculate the phase shift for
_any_ arbitrary load in any arbitrary situation.
and, by the way - i`ve no nst and i`m indifferent to how the variac
influence it - i`ll never use nst in my psu :-D
but variacs - always ;-)
