When I press play the BPM detected by PNW is a few BPM off the value inside the Nerdseq. Eg: if I play the Nerdseq at 128bpm, PNW detects 125bpm. If I slow down/speed up the Nerdseq, PNW always seems to be a few bpm off.
I don't have this issue with other clocks going into PNW (eg: from CVOCD).
I've made a video to demonstrate this - no other modules are used - just Nerdseq and PNW.

Hello,
I did several tests with different devices and couldn't find any differences with the BPM. I also just made a recording with the scope to be 100% sure no other latencies are involved.
Connected is the Trigger which is 4 on the floor. Clock Out which is 1/16.
Putting both on the (HQ) scope shows both stable and calculating the BPM from it gives the rate of 128 bpm. (here rounded caused by the 2 digits after the dot). I definitely would say that the PNW doesn't calculate the incoming BPM well. In fact, this can be a tricky thing anyway if the clock rate/precision is not high enough.

Calculation is simple: Measured frequency (here for the trigger) * 60 seconds
Also, when calculating with the clock signal i get same result as you can also see in the scope picture.
