So, I was looking at this video:

I bought an Actron Dwell Meter (not excactly the same model) and tried doing what Chris is doing in the video. It cured my idle hunting by just adjusting the Fuel/Air mixture by a little bit. I connected to the meter at the same spots Chris is doing on the video, but I'm getting a different result:
During Warmup: (Steady, not fluctuating, RPM steady)

After Warmup: (Steady, not fluctuating, RPM varies a little)

I don't get it, why isn't the needle moving when I can hear the RPMs rise and fall?
I understand that the meter isn't monitoring RPMs directly, but I was also under the impression that the output to the diagnostic plug would/should fluctuate?
Bonus question - why are we supposed to look at the 8 cylinder gauge for a 6 cyl car?
Edit:
This is what it looks like when it isnt powered:
