I do not actually find this to be a good idea.  It's going to be
platform-dependent, or not very accurate, or both, and thereby
contribute to confusion by making results less reproducible.

Plus, what do we do if the backend changes table representation in
some way that invalidates Kaarel's formula altogether?  More confusion
would be inevitable.
