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

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?

The systems would be tested so if there was a difference it would be known. The difference between the systems would likely be small enough to be irrelevant anyway and if it's not could easily be factored into their early season testing.
