Not to be disparaging, but "mHz" is "milliHertz" - "MHz" is "MegaHertz".
If I was at DEC, I don't think I'd appreciate being told that my new
machine runs a billion times slower than it really does.  Of course if
they could get 120 SPECmarks with a 7 second cycle time, that would be
worth bragging about....

I know it's picky, but us scientist types sort this type of thing ;-)
