@avid_dk - good call, though this is purely cosmetic and wont be the cause of not hitting power targets but you never know with Zwift these days!
@Rodolfo_Paiz - I didnt realise the stages didnt have power smoothening and is likely the cause of inconsistent graphs as well as you missing your targets! If I turn off power smoothening on in my Wahoo settings, I cant have ERG on, or at least turning ERG on turns my smoothening back on.
Re pairing screen - I was curious that both Power Source and Controllable were configured to FE-C - but I’m thinking thats not the issue.
As you pointed out earlier, you get your fails when you drop your cadence/adjust power etc - with the Kickr’s at least, unless you stop pedaling or the power target is too high, you fairly much cant fail. So I am thinking your partial fails are related to that lack of smoothening in some way but then I would have thought that if it was an unresolved Stages issue, a lot more people wouldnt be happy.
I found this post - have a look at point 2 Issues with Stagesbike 20(SB 20)
