Default Power valve operation RPM

Does anyone have any information on what RPM the power valve operates on our bikes? Mine is a 2018 xc250 specifically, but I would guess the RPM is similar across many models.

Mine is opening way early (about 2500 rpm) even with the adjuster screw all the way tight. I believe the normal operation should be at 5k or more, but this is just educated guess based on other brands and my snowmobile experience which is higher at 6750 rpm. I am going to dig into the side case and see what it looks like and I will update what I find at that time, but knowing what rpm to shoot for would be helpful.
