Sebastian's answer is exactly right.

I've just opened
https://bugs.torproject.org/33896
because you're right, there's no way the level of precision that
consensus-health reports is at all accurate.

Using the definitions that "precision" is how many digits you're
providing, and "accuracy" is how right you are, I'd say that we're giving
you microsecond precision but not microsecond accuracy. :)
