Don't know about the leak rate which is mask dependent, I think even though it looks about right to me from my experience.

But, those AHI numbers look a little high. The number to shoot for, I've been told, is an AHI of 5 or under. Now, how to get your number to come down may take some adjustments and experimentation on your part or advise from others who are familiar with you and the equipment you are using. Key question: How do you feel? Do you feel as if your therapy is working for you?

My doctor was very optimistic that this therapy would "Make me a new man", as he said when leaving his office. It's only been 4 weeks and one of those weeks I was camping up north without electricity, hence no CPAP. Otherwise I have worn the thing religiously.

As far as feeling better during the day not much has changed. Two things I have noticed is that I don't wake up with a headache much anymore and I rarely have to make trips to restroom during the night. I still get pretty tired during the day, but instead of at 11:00 or so it seems to be 3 or 4 hours later(mid-afternoon instead of late morning).

I can only help from a limited perspective, but those leak rates are on the high side from my experience. We have different masks, but my leak rates are usually well under .1, last night it was .00!

I do know that a treatment goal is to get AHI under 5.0. So, you're a ways away from that range.

When do you have a followup with your doctor? Will he/she read your data? Were you titrated in a sleep lab? It may be that your doctor will need to tinker with your pressure a little bit to get your numbers into a bit of a lower range.

It sounds like you are noticing some improvement, though, and that's great! Some people report that the energy takes a while to return.

To the O.P. Just keep at it. Some people feel big improvements quickly, but this is probably the exception. Speaking for myself, it took a good 4-6 weeks before I starting feeling consistently better. At first it was hit and miss as I was probably paying back a sleep dept accumulated over years. Over that time, the body finds ways to adapt to your sleep disturbances. A common example. Your body getting rid of waste through using the kidneys rather than the lungs. This is my understanding of why people with OSA get up frequently during the night. Plus they'er awake anyway...

The body, being the amazing machine that it is, finds ways to compensated for parts that are working in a subpar manner. Well you're body has gotten used to this pattern, and it cannot usually be chagned overnight (pun intended). It will take a certain amount of time for your system to react and return to a more health state. You can help it along by practicing good sleep hygene, eating right, expercising etc.

If after time you don't get your AHI down, feel good most of time etc. then you'll need to work with doctors etc to find out what else is going on or why the treatment is not working at its best.
