Temporary switching Kickr Core to stationary bike + Assioma Uno. How to match the power


I’m very new to TrainerRoad. Due to work i will have to leave my Kickr Core for two weeks. I know i could use stationary bike in a gym and put on my own pedals.

The problem is that my Assioma Uno is measuring ~10W higher than Kickr.

Is there a way to adjust for this discrepancy? Or is this difference too little to even care?

10W is a lot, especially around threshold. Isn’t there a way to offset power in either trainerroad and/or assioma app?

Change the crank length of the assioma (“cheat”)?
