Congratulations on your first AHI below 5. Way to go!
If your leak line is this consistent from night to night, (seems very good on both nights), then it looks like you have that that under control. The upper line is the total leak, including expected leak from the mask. The lower line is the amount you're leaking over expected leak. If the leak line on either of these graphs were mine, I'd be content.
It looks like you have changed your pressure regime from the first night (lowest pressure 8.0 in Image A) to the second night (lowest pressure 9.0 in Image B). I wonder if that might be part of the reason why your AHI is lower. It looks like almost all your obstructives became hypopneas.
In Image C , it looks like as soon as you hit 12.0cm pressure, everything became stable and you didn't have many events. If you took a closer look (30 minute span) at the 4:45 to the end of the night on image C, I suspect you would see relatively consistent breathing. Of course this is only an hour of information, so it helps to look at the entire night graphs you've provided too.
If these were my graphs, I'd try a few more nights on the current regime and see what the numbers look like, since this the first-ever 2.3 AHI, with a pressure line that is fairly flat across the night. It is my understanding the body takes a while to adjust to a new pressure regime.
At some point after a few days, I might consider dialing up my lower pressure setting a notch to see if I could get rid of those hypopneas, since most of my apneas would be obstructive and centrals are minimal.
Of course, I'm not a doctor, so these are merely opinions. Since you seem to be self-titrating, you are in charge of your own therapy. Good luck withe the tennis balls! I hope this has been helpful.
