Continuing with this metaphor, in this situation you're not the 
pilot making the judgement, you're the aerospace engineer 
deciding that the speedometer in the plane can be off by several 
hundred m/s and it's no big deal.

Yes, every measurement in the real world has a margin of error. 
But, since we're dealing with computers this is one of the rare 
situations where a perfect number can actually be obtained and 
presented to the user.

The right one is the actual speed of the plane and the wrong one 
is every other number.
