I'm pretty sure it's not our imagination... it's more usual for me to
see M larger than N than the reverse (I had assumed it was not meant
as a vulgar fraction of work done since it would typically be a value
greater than 1).

Ahh perhaps the cases in which I've noticed this are poor estimation cases.
