Recording against a quarq and vector3 the neo seems to be affected when repeating an interval at same watts but using a different gear (cog 1 vs cog 10) or pedaling faster. With zwift controlling the power of the neo in ERG it says its the same but the Quarq and Vector3 say the power has changed. GPlama has noticed this too. Also repeated this on a buddy's neo2. On another note his neo2 reads 2-3% low overall to the other devices and my reads 2-3% high.
