I just noticed today (Jan. 3rd, 2015) that I can now log into the zwift.com website. The average power numbers for each of my rides looks to off by a factor of two. I wish I averaged over 500 Watts per ride, might consider professional cycling if that were really the case.
You can add your height, weight, and age to your profile after logging on too. My average watts are way off too.
It appears that the average watts are off if you use “imperial” units. They’re off by the same factor as kg-lb conversion (2.2). If you switch to metric, average watts are correct.
Yes my watts were way off switched to metric and numbers look correct
