I’ve been using TR for around 2 years using a KICKR. I got a Stages PM during the Summer and have just started using the Stages and Powermatch so that inside / outside power would be consistent. After recovering from the drop in FTP (KICKR reads higher!) I’ve now done a few workouts using Powermatch.
Generally seems to work ok and of course I was expecting the power graph to get a lot jerkier compared to the false smoothness of the KICKR.
However, I have noticed that whilst the power is generally in the ball park of the target power the power does often drift up and down quite a bit, sometimes by 15 watts or so. I do try to keep cadence constant (unless Coach Chad tells me to increase it) and based on user recommendations I use the small chainring and a straight chain line in the rear. Looking at the intervals, the variance evens out and I am there or there abouts but often under or over by a few watts e.g. 196 / 193 or 206/200.
BUT when I look at the powerzones I spent nearly 11 mins in Threshold for a Sweet Spot workout. When I checked my previous Ericsson rides (using KICKR as power source) there was hardly any threshold zone and much more time spent in SS
My question - is this variance normal for PowerMatch and I shouldn’t sweat the small stuff or am I compromising my workout because I am spending time working in the wrong zone?
Would be grateful for the thoughts of more experienced Power Match users?
