Question for RemStar Pro 2 With C-Flex Plus Users

I have noticed when looking at my stats in encorePlus under "leaks" (daily) you can select the software to show "average Leak" or "unintentional" leak. My average leak runs about 25.5 and my unintentional leak runs from 0.0 to 0.9 with almost a flat line. Is one reading more important than the other? I am told that as long as the average leak does not go above 40 L/PM I am getting great therapy. Just one of those newbie questions. Thanks
