What I was noticing that some parts of the night looked somewhat consistent and flatter but most of the night had many of what I would call ragged peaks and valleys.
Yes, even with that my RDI is very good, thankful.

I'm right there with you. This is an interesting question.
I can only guess, but my best guess is that it may be partly due to the fact that respiration while we are asleep is somewhat different than when we are awake. And it can change depending on what sleep stage you are in.
I guess the first question to ask is whether your respiration is comparatively normal, or not.
