Sleepyhead APAP 95% Pressure Question

I'm math challenged, which may be why I'm not sure on this. This is my first time trying full apap rather than cpap or cpap-check. I used a narrow range of 8 to 10 based on my AHI on cpap and cpap-check. APAP gave me my first flow limitation since I've been on a machine that checks them (since 10/2015), which may be just coincidence; who knows. But my question is in the chart on the left for pressure it has 10 for 95 percent, but from the graph it doesn't look like I spent 95 percent of the night at 10. (My AHI didn't change from what it usually is. I'm just doing an experiment to see if it makes me feel any better on APAP.)

Where is my thinking wrong on this?

Thanks.

Your thinking is not wrong and that is why it is helpful to see the graphs. The 95% means you were at or BELOW that number for 95% of the time. You may have been very briefly at the top number. So that is why looking at the graphs is helpful, you can see where you were most of the night.

Thanks a bunch, OkyDoky!

here's a really good explanation of what all those numbers mean, mathematically:
