Ignoring the rules, and based on the OP's complaints, a bump of about 2 to 10 to start and see if relief occurs then evaluate from there. By 2 to see if that makes a difference, if not at least a small difference I may be barking up the wrong tree. Thus always the need to evaluate between steps.
Look at Titration protocols for a BiLevel, then just think of exhale pressure applied and inhale pressure applied.
Use Exhale pressure to manage OA events increasing in small increments, typically 1 cm. Repeat as needed
then use Inhale pressure to manage hypopneas, RERAS, and Flow Limitations. Same thing, small increments, typically 1cm.
EPR changes the difference.
Typically the user is over-titrated meaning too much pressure so I rarely comp for the drop of exhale pressure on the initial EPR setting but look for a change in the OA results to see if I need to compensate.
Many will find that they need more pressure than 4 or 5 so I typically suggest a start of at least 7 so EPR can be fully functional. Also it is more difficult to determine the effect of EPR if that value is fluctuating because min pressure is not at least 4+EPR.
I hope that helps some
