Quick queston - I’m running a Quarq power meter (crank spider based) and a smart trainer (Cycleops Hammer). What I am seeing in my workouts is that if the target power is 180 watts, then my actual power is about 10 watts higher. I have calibrated my power meter and done a spin down on the trainer. Not sure why I am seeing this other than maybe my numbers at the cranks would be higher than at my trainer due to drive train inefficiency.
But not really sure why this is. It’s been resulting in XSS scores significantly higher than planned which makes it hard to manage to a training plan.
Anybody have any ideas here?
