Where do all of the numbers come from?

I'm new here and have been using a Respironics M-Series for about 4 or 5 months. In numerous posts here, people quote their AI, HI, Leak, etc. numbers. Where are they getting those numbers? When I flip the top door on my machine, there is essentially a screen that tells me the average hours of useage per night over the last week and a second over the last 30 days.

Is there something that I'm missing or was there some upgrade that I should have purchased?

Thanks. BTW this is a great Forum
