.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??
