Hey guys, so decided to compare my stages PM to my H2 PM yesterday. Was doing pioneer -2 in ERG mode so I turned on my wahoo and just watched the Stages 3sec avg power through that and compared it to the 3sec avg power that I broadcast to Zwift while I do my TR rides.
I noticed in the beginnig the power was off, stages was about 10-15w high during the warmup while trainer was cold. As things got towards the 10 minute mark they started tracking closer together, but the Stages was always more “jumpy”. As an example
TR had me doing a 4 minute interval at 220w
Zwift (mirroring the H2 PM) was showing my 3 second power anywhere between 215 and 225 as it “floated” which is normal
Stages showed my 3 second power anywhere between 210 and 230, sometimes dropping as low as 200 momentarily, and as high as 235ish momentarily as well.
If I made an effort to really spin super smooth they tracked within about 5-6w of each other, but normally pedalling the stages seems more “sensitive” than the Hammer, which I guess is to be expected? I just want to know if this behavior is normal. I understand they will never be 1:1 perfectly together but also want to make sure there’s nothing wrong with the PM seeing those larger dips and spikes. I got the H2 new, but the Stages I got used, so if there’s any potential doubt I have it definitely lies with the Stages.
