I'm also clocking a Pamela's New Workout with the nerdseq and have the same bpm display difference. The timing is solid though, so I've just been ignoring the display. It appears to be a problem between pams and other devices as well:

There's mention of calibration in the PNW manual to fix the bpm display - I haven't tried it but that may do the trick.
