The IP position is not the way to set the IP timing. The marks cannot be used for anything but extremely rough guessing. In fact, we like to have the IP positioned rotated outward from the head, to make future replacing of the rear glowplugs easier.
Couple questions for you:

Did you use Volvo tool 5190 with a 0.2mm feeler gauge or similar or did you eyeball it?

0.92 is fine but did you measure this while the cold start device was deactivated?

Yes me too, it should only be running better. We need to go thru it methodically. It's really not that complicated but the process does require special tools and unorthodox procedures to guarantee success. Many many have tried to "cheat" and use commonly accepted mechanics practices instead and failed.
