I'm also concerned about therapy induced central apnea with the high pressure of 22. Is there a cause of concern? Or am I just being paranoid?
Paranoia. Not a concern. That said on just about every chart I look at I first look at the AHI, the overall guide, then the CA index, then everything else. That is because CA just needs extra TLC, and a bit more caution. Always look, but don't worry. If it gets over 3, ask, just to sure it is seen. I'm not saying that is bad, just that it need a bit of study.
If you do not have a CA issue, and CA makes a BIG jump, it just needs to be looked at, nothing more.

What I see in your results is a persistent flow limitation which would be better treated with pressure support. The fact the EPAP is nearly unchanging, suggests you may tolerate a lower EPAP min pressure. My suggestion is to drop EPAP min to to 14 and PS min 3.0. There may be more room for dropping pressure, but let's start here and see how you feel. I'd rather see you comfortable than chasing numbers.
Sleeprider:
Woah! Changing my EPAP to 14 and PS min to 3 resulted in my lowest AHI (0.45) ever!
As far as how I feel, I didn't feel any change as to how I felt prior to the change. I still awoke feeling rested.
About my flow limitations, I don't know how to read the data there yet though. Did that improve?

There are very few obstructive events. Let's continue reducing minimum pressure until there is an increase in the OA and/or H events. Drop 1-cm per night until you see the machine is busy changing pressure, or a higher event rate. You have some flow limitation, but to address that, we would need bilevel or the Resmed machines which offer EPR which is a true bilevel at 3-cm pressure support. Since reducing pressure from 16 cm minimum, your event rate has improved and your tidal volume is unchanged. Your respiration rate is nearly the same, and somewhat high. We would need to see a close-up of the flow rate (2-minute segment) to evaluate the actual respiration rate and to see if there are irregularities in the respiration wave. If you post a 2-minute segment of a flow rate, we can take a look and let you know. That said, I don't know of any settings on your CPAP that can alter the respiration rate.

Thanks for the reply Sleeprider!
Attached is a 2 min zoom of my flow rate from my latest data.
I also already have a bilevel machine (Dreamstation Auto Bipap), at least that's what I've been led to believe!
