Thoughts on my last few nights
I check my stats every morning.. I am always less than 1.0
The last 2 nights I have been over 9 and 7....
NO leaks what so ever..
My wife even told me I was snoring during the night last night.
What could be wrong.?

Looks like your cutting off your airway by tucking your chin in. A lot of people here use a soft cervical collar to prevent this. You can pick them up at any drug store or on line. I use one and it works great.

I'm going to suggest that you expand the cluster of OA events so we can see more detail

edit..yes, a propped up pillow can do it
I also think you are maxing out the 15 too often and I would have 17 as my max. The unknown at this stage cluster, was also looking for more pressure. Do they happen very often? As said, sometimes a collar can help to see if chin tucking is a problem, sometimes a change of pillow is then enough, sometimes the collar still needs to be warn

For auto-cpap, from machine data or software. You can set the min pressure 1 or 2cm below 95%. Or clinicians commonly use the maximum or 95% pressure for fixed pressure CPAP, this can also be used for min pressure.

RE: Thoughts on my last few nights
The clustering of events is pretty classic for the chin-tuck obstruction. The idea is to get a soft comfortable collar that gives you a fairly loose fit around the neck, and a comfortable height that will prevent your chin from tucking down to where your airway is occluded. You can probably replicate this obstruction by relaxing in a chair and letting your chin drop down. Do you feel the increased breathing resistance? You are arousing during this event, and doing recovery breathing, and the pattern repeats until you change position or sleep stage.

Since you have not had this problem often in the past, you may just need to retrain yourself to avoid the positional apnea. I don't think this is a problem with settings, and it seems you stay pretty close to your minimum pressure until you have these obstructive episodes. Ajack's suggestion of higher maximum pressure does not seem like it would hurt, but it may not overcome positional apnea.

RE: Thoughts on my last few nights
I would leave it at 13 for now and focus on getting your chin up and your head back.
