Take a view on your car and engine.  How long are you going to keep
the vehicle.  If you follow the "90,000 mile" guideline on the belt,
you'll have to keep the car to 180k to change it twice.  If your ideas
are more like 120k - you'll change it once at 90k and then drive only
30k on the new one.  You would minimise your own risk by changing at
60k, no matter what Audi's advice is.

I've come to two conclusions:

a) Physical (external) inspection is not conclusive as to belt status.

b) Above 55k miles, the risk of belt failure is uneconomic.

How far you can drive without changing the belt - I bet we could find
someone on a 200k engine who's never changed it.  Doesn't change my
55k to 60k view.
