In real life, that's well inside measurement/manufacturing/modelling tolerance.
I agree it is not going to make much difference. I just noticed it and wanted to point that out.

Fully open position has only relevance as a speed break or on the ground for example, in prolonged run up.
Exactly.

I did not think the overheat modeling was realistic at all. In general these airplanes are designed to fly with radiators closed or in the least drag position (straak) and keep the engine cooled at maximum continuous and below.

It is only in overboost conditions, high density altitude, and stressful operations such as climbing that the engine temperature becomes an issue. I tried the Spitfire Mk I out and it ran at maximum temperatures in level flight in cruise settings.
