last night I was doing the trainer road ftp test on my Kickr. When I got to the 5 minute test and the 20 minute test in slope mode my wattage was reporting very inconsistently. It would go from 275 to 255 to 235 back and forth and so on. Is that normal? Is my pedal stroke that unsmooth? Is the reporting on the wattage to TR inconsistent?
I was also running Zwift in the background so I yanked the dongle for zwift incase that was interfering(both TR and Zwift were reading the same wattage) that didn’t make a difference. TR was running Bluetooth and Zwift was on ANT+ on different devices. I kinda got pissed off and gave up because I thought I was wasting my time and dropped my wattage for a couple of minutes in the middle. Then I decided I might as well finish out the 20 mitnutes for a hard workout and the experience for next time when I figure out the wattage. I ended up with a suggested ftp lightly lower than my currents so I’m sure had I powered through the 20 minutes I probably would have raised my ftp.
I know Zwift shows average fpt during a 20 minute test so maybe I should try that and not freak out about the inconsistent readings.
