And I'm ok with that - it clearly wasn't going to be solved in time.
Shame though.

Certainly Nm is covered. I've never seen a Nmrad before, so no idea!

Doubtful... This one seems like a real corner case and I'm not sure it
would be worth covering in any languages implementation. Seems like
we'd be letter "best" be the evil of "good enough" here.

Certainly the reference implementation has Bq and Hz defined
separately.
