	I presumed the /same/ tape measure was used for the initial 1000 ft
measurement, and that this tape measure is fairly in-elastic... Such
that even your 0.1% error is constant in the first 1000 foot -- that is,
any error in the original 1000 feet is reproduced by the use of the same
tape. And that, in turn, would mean only the last foot difference would
be off, and the error would be in scale (if the 1000ft is 0.1% short,
the 1001ft is also 0.1% short of the total); but not that the first
distance could be short and the second could be long.
