Funny how you can look at something all day sometimes and see nothing... 
or only what you want to eh ?

Ah... this is easy... obvioulsy you want it to stop the damper from 
banging into anything on the way out... as in the lower half banging 
into the strings... or the head banging into the hammer shank or 
something else.

Then you also want to avoid it actually moving out much more then it 
moves when engaged by either the pedal or the key, as there is no need 
for any more motion  and this can easily end up being felt to 
prominantly at the key.

But then...  it has to be able to move enough so that it does not 
inhibit either the pedal or the key in any sense. 

Ideally, the damper lever should be fairly parallel with the string 
plane and the damper lift from the pedal should be just the same or 
perhaps an 1-2 mm greater then normal key play.  Add to that about 3 - 5 
mm of travel for the stop rail... and all should be well.
