I’m on an Elite Zumo - haven’t ran a calibration test yet (that’s my next job).
The bike itself is a hard tail mountain bike - about 10yrs old Specialized and in major need of service - gears are very clunky. What I’m getting at is it’s not a smooth changing, leaning forward road bike, it’s a bike seen a lot of miles on dirt tracks, crank & derailleurs bashing into logs etc
So it’s not perfect but just wanted to check those results were average for my setup.
I think you should definitely do the calibration before you look too hard at the numbers. I recently got a new smart/control trainer and I was very anxious to try it out in zwift. I sort of glossed over the calibration steps and jumped right in to zwift. The thing worked okay, but the numbers were sort of screwy. I later did all of the calibrations and setup properly and next time I rode in zwift everything worked much better and made more sense.
