Yes, grope, it's always like that. This is why the vast majority of heating curves are not precisely adjusted!
The heating engineer puts the approximate coefficients according to the heating mode (radiators, heated floors, etc.). He cannot do better.
The adjustment method is effectively "pifometric" and requires time. It's normal.
I described it in the long thread on the functioning of the Okofen pellet boiler, I believe ...
But once set, whatever the outside temperature, you will have the desired inside temperature (except "disturbances" by a stove, a sunny bay window), etc ...
