I think that is a sensible approach. There are too many people who seem to be afraid to use their own judgment. It is not helped by misunderstanding the crucial difference between "Best Before" and "Use By", and recognising that safety margins are added.
In previous fridges I have had problems with salads and the like freezing, and found that the one place not to put lettuce was in the "crisper" drawer - the coldest spot.
The Miele has an optional circulating fan, and leaving this on, although there is a small energy penalty, ensures that I have never had any freezing anywhere in the fridge compartment.
