Calibrate once, or on every paired device?

I have an 820 and a 935 that I pair with my new vector pedals. When doing a pre ride calibration, should I only do it on one device, or both? If only one, does it matter which?

You only need to do it once as the calibration and offset is performed on the pedals and not the head unit.

The only power meter on the market that you need to do it on each device is the crank based SRM as the offset is applied by the head unit and not by the power meter.

Thanks for the reply, just what I wanted to know. I’m new to power meters so it may seem a silly question. Cheers.
