Stages vs kickr in ergo--which is more righter?

According to my stages PM, my wahoo reads about 8-10 watts high in ergo. Which of these two devices is more close to right? I zeroed both of them.

I don’t really care, just curious.

I don’t really care either but I think your question is awesome.

The stages is more lefter

And jackmott wins the day.

Crank vs hub though, of course.

The stages is more lefter
I’m impresssed

Yeah if we assume both are accurate and your left/right split is perfect, we would expect about 3% more watts from the stages, depending on the state of your drivetrain. (clean and lube your chain, see if they get closer!)
