I am catching on to the AHI data
The birthday candle (not the 100W light bulb) above my head has flickered on about what the cpap data, and members here, is telling me.
I reviewed all the data from April 1st to last night a see that with one nights exception, my Clear Airway is 0.0 that I take means cpap machine successfully keeps air moving through my mouth and tongue out of the way (little no snores).
The Obstructive and Hypopnea numbers keep jumping around and can't be controlled readily by the machine I have. When it does a high pressure burst (to initiate breathing?), that air just vents out the mask, no matter which of six masks I have. And my respiration is shallow low titdal pressure.
I will point this out to sleep doc and see what s/he says.

I think the "High Pressure Burst" you are talking about is just your machine seeing if you need a higher pressure. (would help to see a chart)

Your Cpap machine does not treat Clear Airways. A Clear Airway event means that your brain is not sending a signal for you to breath. When this happens, the Apap will not raise pressure to treat this event. It's good that you don't have Clear Airways.

Obstructives and Hypopneas, snores, Flow Limitation are normally treated by raising the minimum pressure.
Air is supposed to vent out of the mask vent, otherwise you would be rebreathing the same air. 
Low tidal volume and shallow respiration should be discussed with your doctor.

What I meant was not out the mask vents rather the annoying "farts and burps" out side/top/bottom of masks that awakens me (again and again), no matter how tight the straps. And if too tight then I get very little sleep as the pressure just keeps me awake.
As an aside I took a nasty fall that my wife had me checked into the hospital because of confusion and momentary blackout, where I stayed overnight for observation. The CT and MRI scans showed I suffered a slight brain bleed which the neurosurgeon says should not be a concern. But you know, I had the most refreshing beautiful no cpap sleep in two months. I awoke so refreshed and relaxed I couldn't believe it. Last night, on the torture device, my AHI zoomed to 33 with Hypopnea being the big number, and I felt like CRAP today. Go figure.
RE: I am catching on to the AHI data
Have you tried mask liners? Some here say it helps with mask leaks, or try a different mask style.
Have you tried a higher minimum pressure yet? I think you need to take control of your therapy.
You've been given alot of good advice.
Would help if you could post some recent data. Try to keep it in one thread.
Sorry to hear about your fall, please take care.
RE: I am catching on to the AHI data
Try a fixed pressure, the pressure changes of the Auto program may be allowing leaks. At a fixed pressure it could be easier for you to find a mask fit that is leak free.

Thanks, I am waiting to talk on June 1st but don't hold much hope sleep doc will have anything useful to say even when I point out the central apnea problem as possible cause of high AHIs. Will probably blow me off as reading too much Wikipedia or relying on Apnea Board info as "alternative facts"!

Why do you think you have central apnea? In your first post, you said your CA reading is 0.0.
Post some data here, we can advise you "before" you see your doctor.
RE: I am catching on to the AHI data
I think you have to take your own control of your therapy. The Drs and sleep clinics do have the time nor the inclinations to daily or weekly adjustments. To them, if it's under 5 AHI it is treated. Anything else you are on your own. To further this attitude, ResMEd in their Myair program does not deduct a point even for AHI over 5, yet deducts points for taking off your mask to adjust it. Go figure.
