In this day of digital displays, the geometric non-linearity of the physical tank should be pretty easy to program out of the meter, so that is pretty frustrating.

Any chance you drove the car considerably harder for the first half of the tank?  If not, that is way off.

It's cool to hear that you are so enamored with the RS though Nick.  Spank her for the rest of us with humbler garages.

No to mention mine doesn't seem to know about my 90 litre tank.. It stays on full for ages then drops like a stone.

This must be a faulty gauge. I had this issue on the Audi and it was fixed under warranty. The problem often starts after overfilling the tank.
