I don't like to think about it. I gives me a headache.

 "...What would be a suitable
 value of step-start R to limit the inrush current to 50A-rms?..."


 In this practical & real world, it would be 4.6 ohms.

Congrats, Roy.   The closest value in my junk box was 5.6½s.

2nd question:  What would the approximate inrush-I be without a
step-start relay and resistor?
