Rick,

I don't see why you can't both be right.  I think the variability in NST
manufacturer's construction methods (wire gauge, core sizes, shunt
effectivity, etc.) could make both results possible from different
transformer types.  A water load should behave like a "real load" at 60 Hz
unless you are generating a lot of H2 & O2 bubbles at the electrodes at
higher currents.
