I don,t use VPAP Auto but as ResMed say high leak above the red line affect the accuracy of the data.
I saw that on the graph and wondered what that meant. So he's got a major leak problem most nights?

ok the red line sits at:
0.4L/s = 24L/m
Your at 36L/m with a maximum of 96L/m
With your leak rate up and beyond the red line your data is corrupted and cannot be taken as read. The AHI readings could be correct but with such a high leak rate the only person who knows whats going on is YOU! Ask yourself this.

AHI is declining over the couple of months shown in the summary info, so that's good, therapy is working. Congrats!
Leaks are... less good. Your 95th % numbers are too high, 36 for leaks will probably mess up the AHI results, etc - but your median numbers for leaks are pretty small. That number is the average, once the highest and lowest numbers are removed. Looking at the 2 days of detailed graphs, I can see that you're having periods of an hour or more where the leak numbers are over the "red line" - if it's the same for your vpap as for my apap, that line basically means that the leak is beyond the machines ability to compensate for it.
So, from that, my first recommendation would be to get the leak under control. Go back to your DME/RT/whatever and show him those graphs. That mask is definitely not working for you, at least, not as-is. Most places will let you try different masks until you get one that fits just right.
