I was recently perscribed a CPAP (ResMed AirSense 11 ELITE) and discovered this forum short after. I ordered and SD card and tracked my results for the first time and attached them below. While this is only 1 days results and I am still getting used to having a pillow mask on all night, is there anything I can read out of these graphs to optimize? Thanks for any feed back.

Thank you for clarifying that. I was a bit confused because the manual said autoset elite so I thought it was both. I have updated my profile to reflect that it is autoset.
Your 95% Flow limitation reading of .12 is higher than we like to see.
The Flow Limitation is what causes your pressure to rise to 15cm (maximum set), and can cause sleep disruptions.
And where you see Flow Limitations, you usually see Hypopnea. To help with this, we advise the use of EPR. I suggest trying EPR 3.
In order to receive full benefit of EPR 3, your minimum pressure of 5cm should be raised closer to what your median pressure shows.
If you're willing, make the following changes:
Set Minimum pressure to 8cm.
Keep Maximum pressure at 15cm.
Set EPR to 3 (Full Time).

I have included an updated screenshot of my latest night's sleep. My flow limit has dropped by a half in the attached screenshot and has been a third on other nights. Discussing with my provider, she stated that having 0 AHI is very rare so the AHI I average now seems good compared to 16 in the sleep study. I am not sure if there is much else to be improved upon so please weigh in if you can interpret the graphs better than me.
Even though I only slept for about 5 hours, I felt well rested and felt that I actually got sleep after waking up. Needing a 30m or so nap in the middle of the day still feels like a necessity. Using a p10 mask, the hose that goes down the bottom of the face can get annoying sometimes. I believe my sleep time can improve further once I get more accustomed to sleeping with a mask. At my 3 month mark, I can get an AirFit N30i (nose cradle and tubing out the top) to compare its comfort.
I will be receiving an Oura ring this week. I understand that the ring's ability to track sleep is not perfect but is considered to be one of the best on the consumer market. It will be interesting to graph my sleep cycles and see if sp02 drops compared to what was documented in the initial sleep study.
Everything looks good! Stay with these settings for a few days to see if this is a trend.
Your provider is correct in saying that an AHI of zero is rare. It is nice to see, but I feel that the most important thing is comfort and how you feel the next day.
In time, you may want to wean yourself off the ramp feature, or at least set the ramp closer to your minimum pressure instead of starting at 4cm. Sometimes, that can cause an "air starved" feeling.
Your median pressure in this chart is around 9cm. So I would set my ramp to start at
6cm. Just more of a comfort thing.
