Use the cursor instead of MEAS statements,
        which are so easily wrongly-written.

        .TRAN for 1010ms made no difference; same
          measurements at 1005m as at 5m
         
        
         
        Two things I notice instantly:
        Primary voltage should be 311V. Voltages in SPICE are peak.
        You don't run a 50Hz transient for only 10ms.

          Please see my recent upload,
            Autotransformer.zip
           
          I need some tutorials regarding
            autotransformer modelling!
          I was intrigued by Hassan's AC Stabilizer
            and tried to model TR1
          The model differed from my expectations
            in several ways.
          1: Why do the
            tap-to-tap voltages differ, with equal inductances?
          2: Why is the
            separate 18V winding so different?
          2a: Why is it
            more different when I separate the Kxxx directives?
          3: Why do the
            outputs throw infinities with small or megohm loads, but not
            when 1G or open??
