The error caused by the higher voltage (i.e., 1.5v instead of 1.35v) is not
linear.  At higher light levels, the error is over 2 stops, at lower light
levels it's less than one stop.  All the adjustments built into the OM-1's
are linear, so there is no way to correct by simply "recalibrating".  Even
if you split the difference, your high and low exposures will be off a stop
or so.
