So, on load you get less than rated output voltage.
Thus, the voltage ratio changes between no load and rated load.
The turns ratio doesn't.
That was my point.
It does when you move the tap changer.......

Spot on...ole chap.
In the US taps are far more common than not. Not one but usually 5; 95, 97.5, 100, 102.5 and 105% of nominal voltage.
