Vector 3 suddenly adds +/- 50W

My Vector 3 suddenly gave 50 Watt more average power on 2 almost identical trainings with less than a week between them. 1st training 149W, 2nd training 195W. All the other trainings were consistent around 140 - 150W on average. What could have happened? How do I know what is the correct measurement?

It would help to have more context to try to figure this out.

Is this on an outdoor ride, or on an indoor trainer?

Outdoors: Wind can make a large difference to the power required to do a given speed.

Indoors: If the trainer is controlled by a computer, then it could be that the trainer resistance setting is not always the same. Tire pressure plays a large role (for all wheel-on trainers).

For Vector 3 itself: What head unit (display) are you using? Do you do a static zero calibration at the start of each session?

Maybe you are just getting more fit?

This also happened to me...felt like superman...I fixed it by calibrating before any ride, indoor or outdoor.
