Remote calibration - anyone done it in just one go?

Anyone done a controller calibration in just one go? I got a warning on the remote saying “EMI 2 Return sticks to centre” so after a quick google found if I done a controller calibration it should fix it.

I charged the remote battery then sat down to calibrate it, half an hour later I was still trying to do it becasuse every time I got near the end it would time out. My fingers started to cramp up and I was getting very pissed off. Is there a certain way to do it cause following the blue circles is near impossible.

Btw I did eventually do it and touch wood :point_right::deciduous_tree:the warning has not come back.
