Yep, exactly. I had the Quarq paired to my Edge computer displaying power & cadence and then paired just the GSC-10 to my fenix 3 to compare the values. Held the two side-by-side and could see in real-time that whilst holding a fairly consistent spin, the GSC-10 was fluctuating +/- 1 rpm, whilst the Quarq was more like +/- 4 or 5 rpm.

I did this on a few occasions whilst troubleshooting it, but this is what convinced me that it was the Quarq's cadence values that were noisy and not just my inability to hold a constant spin! I appreciate that the two sensors might smooth their reported values to different degrees, but the fact that the Quarq managed to fix itself suggests something else.



You might be right on that, I vaguely recall reading somewhere that it wasn't but I could be wrong; it's not something I've looked into because it's not a route I think I need to go down at the moment.
