I have a “dumb” trainer. After looking online for folks who have made their own calibrations in excel and have found the Cyclops power curves to be slightly hope inspiring, rather than “accurate”, I’d like to hear what the zwift folks did to create a power vs. speed correlation…or is that too proprietary to ask of? However after using gym equipment during a short stint about a year ago, I would say Zwift did a good job. Or at least if the gym equipment was calibrated, as that is the standard I have gone with. Zwift power readings seemed to closely match my average power output from the gym elliptical trainer with a relatively similar effort. Anyways, you guys are making a great “video game” to help make the mundane a great activity, and one that challenges you to push harder! great Job so far! Looking forward to seeing what you come out with next!
