DME is slant range, ATC may be horizontal. How high were you?

I was at 2000 feet, which is about 1700 AGL.

Certainly not enough to give you an extra mile of slant range.

That was my thought in flight, in which I queried approach and asked him to
verify my distance.

Never noticed a problem before, and wondered if DME's can lose their
accuracy.

I didn't have the time to reprogram my GPS as I had to fly the plane, but
if I had the time, that would have been my next step.
