The Campy Record Stages power meter reads ~20 watts lower than my Powertap G3 hubs (on two bikes) and the Campy Record power2max NGeco. The Powertap G3 and power2max have almost identical output readings.
hmmm.. the 20 watt differential sounds really high (eg. compared to the above youtoob review that was linked). I'll have to compare to my trainer's PM after I install to see how I fare. I guess if it is consistently off by X watts, you can work around it.
