The stock air pressure calls for 10.6 bar.
Ive seen a few of you suggest you were more comfortable with it down to 10.3 and even lower.
Forgive my ignorance, as Im trying to learn/understand suspension better. But shouldnt the air pressure be set based on the weight of the rider?
And then play with the rebound & compression dampening from there?
Is there a chart that has recommended air pressure based on weight?

According to Race-Tech’s calculator...
10.0 bar = 146 psi ... 170 lb rider
9.6 bar = 140 psi ... 150 lb rider
Shouldnt spring rate be based on rider weight and that alone? (save for the drastic differences between MX & SX)
FWIW I would start the day at 10.3 bar. 2 hours of ride-time later it’s dropped to 9.8
The bike was far more comfortable to ride at that pressure. Which would coincide with Race-Tech’s recommendations. Then again, 2 hrs into a riding day and anything should get easier by proxy.
I’d love to start playing with the clickers. But I want to start from the right PSI first.
I had a few problems with the fork not using all of its stroke when i had 10.6-10.8 bar and adjusting the clickers didn't help that much. So i lowered the pressure a lot. To 10.0, problem solved.

Yes, you are right that to an extent the pressure should be a 'set it and leave it' setting (once you have found a pressure that works well for your weight/style etc)
But one of the advantages with air forks over spring is having the ability to easily change the air pressure. This gives you more tuning options which is particularly useful when riding a variety of conditions, say from sand to hardpack, or from a natural track to a very jumpy track.
Set your clickers somewhere in the middle and then experiment with air pressures first. Measure your fork sag and/or use a zip tie to keep and eye on how much travel you're using as a guide.
