You don't say how.

Did you interpret it, or convert it to PostScript and inspect the result?

I'm working on a rewrite of groff_out(5), but even in its existing state, it
can be followed. If you want to argue over the magnitude of small movements
in *roff, at some point you're going to have to familiarize yourself with the
device-independent ("intermediate") output format.

I didn't see any reason to do so. Vertical motions are generally not made in
ems in typography, as I understand it.
If you won't look at the output, look at the source.
