Six sig figs... impressive. I was under the impression the scuds were not quite built up to that level of precision.
This is to some extent meta-humor as the whole point of the story is the programmers involved needed an engineer helping them who understands sig figs and the effect of built up error tolerances.
I can only hope that for the sake of my post that my lack of attention to the increase of perversion of the velocity of the skud missile does not in some way invalidate my claim :P.

Which looks suspiciously like a rounded "3750 mph to meters per second" conversion. Indeed, "scud 3750 mph" turns up a lot of hits.
