Hi, thanks for the quick reply!
I appreciate that the tests can be basic and get different results but the difference here can’t be because of indoor vs outdoor. I have only ever done the tests indoor (I’m fairly new to the testing). However when I view the file on Strava I can see my average power for the 20mins was 232 W which by taking 5% from this would leave me with an estimated FTP of 220 W, however the Virtugo test results gave me a score of 214 W. I know that this difference is small but it just made me wonder.
Similarly when I did the 8 min version, Strava has an average power for that 8 min segment to be 261, 90% of this is 235 W yet the result came back as 229 W.
Is this just a difference in estimated power between Strava and Virtugo or something else?
