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

I doubt that Stages as is, is accurate enough for Sky, but I don't know enough about power training to know if this genuinely matters. (My view, which I'm happy to be disabused of, is that as long as you're using the same product for all your power training purposes, then the actual genuine power figures don't matter, as what you want is consistency).

I would have thought they need to be able to translate between the two systems. I.e. sky train grunt #2 was producing x watts at this stage last season on srm now he is producing y watts with this new meter. The question facing brailsford et all will be; Is that because he has different fitness levels or because they changed the measuring tool from srm to stages?
