If there is AF testing of a finished camera, you will go through a large number of shutter activations. The Reiken FoCal system runs about 600+ shutter activations for a single cycle. I expect there are other systems available and used by Nikon and repair shops and have no doubt they generate similar numbers of activations.
In the scheme of things, 1200 activations is small compared to a 200,000 cycle shutter. How many activations will you really use over the camera's life - 50,000? Unless you are a collector and won't be using the camera, it really should not matter.
