Power, especially short-term power, is way too unreliable to be estimated from crude GPS data. Even the iBike, which has accelerometers (for grade and translational accelerometers), pressure sensors (for wind speed), and careful coast-down calibration runs, has difficulty with short-term power.djconnelhttps://www.blogger.com/profile/01484858820878605035noreply@blogger.comtag:blogger.com,1999:blog-1564958057737541664.post-91865621446950137622011-12-05T07:27:28.666-08:002011-12-05T07:27:28.666-08:00Dan, is your suggestion publicly posted (i.e. in S...Dan, is your suggestion publicly posted (i.e. in Strava's support forum or similar)? If so, do you have a link to it? I'd like to chime in on it. Their calculated power for my best efforts deviates significantly (like, 2x in some cases) from my best measured efforts, which, unfortunately came some time after I'd already been using Strava for a while. Now the crappy estimated power ones are what's showing for my "best efforts" and there's no way those are right. I just don't want people getting the wrong idea about my abilities when they read my profile :-)Joshhttps://www.blogger.com/profile/05698932814424984195noreply@blogger.com
