I have not measured but I can see the o ring is half way when sitting on the bike. Regardless of how much psi is put in. Only differnce is felt firmness if I cycle the shock with 10 small compressions then add psi which actually feels like it’s gradually adding psi to the shock to increase firmness with no effects in reducing sag though.
If I compress the shock 10 times before adding more air to equalize the negative chamber it feels like psi is actually going in but still reads 200psi regardless ever I pump air into the shock remove the shock pump and reinsert it.
But I do feel like the shock has a bit more resistance firmer feel but still can’t get the recommended sag setting adding psi.

Can you borrow a buddy's shock pump? I've had a couple shock pumps lose accuracy on their gauges. If it feels firmer, sag should definitely be changing. Try ignoring the psi value and pump it until you get the correct sag %.
I figured it out I used the pump that yt gave and really tightened it down when putting psi and it worked I was using my own other pump and you just have to make sure the pump is really tight when screwing it to actually get accurate psi reading and actually put psi in the shock
When tightened down good each pump barley puts any psi in and that’s when you know it’s working
You may also want to consider adding a volume reducer. There are a few good videos on You Tube on how to do it. Cam Zinc did a video in which he installed a reducer on the DPX2 on his Jeffsey. It is not necessary to remove the shock from the bike. Take out the air in 50 psi increments and compress the shock between each increment(the same way you should be inflating it.)
