Last night while riding Richmond I came across another rider avatar which was moving with constant 2.4 w/kg on the flats without pedaling (legs were not moving at all). At one point his avatar even changed position on the bike tacking in on the top tube like for descending faster even though he was on the flat at the time. More than that I was moving at 2.5, 2.6 w/kg and the guy just passed me with that steady 2.4 w/kg. He dropped me slowly and he continued moving passing other riders without pedaling at all. In some area the rider went up hill again without pedaling but at constant 2.4 w/kg. Is this some sort of bug in Zwift SW or is some sort of cheating? How can somebody input a steady 2.4 w/kg at 0 cadence (I assume his cadence was 0 because his legs were not moving)?
In the two or so kms I was around the other rider he din not pedal once and the w/kg was constant at 2.4. My W/kg was permanently changing between 2.4 to 2.7 w/kg.
