Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Interesting conundrum, I hadn't considered it before, posted on wattage about stages. And a clear issue, drawback.

Stephen - I had the same feeling that data from my stages did't match with what I expected from experience with a PowerTap, then I got the Garmin Vector system and did a ride with it and Stages at the same time - it was clear that Stages was underreporting, as less then 50% of my total power was generated by my left leg - Stages doubles left leg power to estimate total. Vector measures left and right then adds together. I posted the data here (https://groups.google.com/forum/#!searchin/wattage/stages$20vector/wattage/fJ42Uon52Z4/LJnuTgyxoGYJ)
