Agreed.
Most efficient is to set the boiler temperature low
enough such that the room stat never quite switches off.

That may not be true..
my boiler is most efficient at full output and is a few % less if the output
is reduced.
Don't ask me why, that is what the manufacturer says.

I suspect full output is referring to burner power, not
the water temperature.
