![]() fit files from two different power sources easy. ZwiftPower has a tool accessible under Your Profile>Analysis which makes comparing two. ![]() The reviewers will analyze both sources of data to confirm that the power readings are accurate. Providing a second source of recorded power data will, in many cases, streamline the performance verification process. … riders are strongly encouraged to record a second source of power data. Race Verificationĭual recording is especially popular among top Zwift racers because it streamlines the performance verification process. Zwift doesn’t currently have the ability to record two different power sources, so riders will record one power source on Zwift, and the second on their bike computer (Garmin, Wahoo ELMNT, etc). It’s called “dual recording” in the land of Zwift because riders are recording the data from two different power meters. If those are the numbers you see, chances are both power sources are quite accurate. It’s not a fool-proof method either, but what you want to see is your bike-based power meter (usually pedal or crank-based) reading a bit higher than your smart trainer due to small friction losses in your drivetrain.Įxample: if you’re putting 250 watts into your pedals, and lose 4% through your drivetrain, your smart trainer should be reading 240 watts. Experienced riders can sometimes “feel” if the numbers aren’t accurate, but this is far from a reliable method, and it doesn’t help newer riders who haven’t trained enough with power to know what holding 2.5w/kg or 300 watts feels like.Ĭomparing the power numbers from one power meter to those from another helps ensure that both are accurate. It’s impossible to know if your power numbers are accurate when you don’t have another power meter reading to compare them to.
