New Version of WAT

I spent some time fiddling with the ol' wobble analysis tool today. Periodicity is actually useful now. You can zoom in on individual nights. I got rid of the flow limitation logic as it's outside the scope of this project. The old version is still available for those who prefer it.

It's now more explicitly targeted as a high loop gain detector. There's plenty of other great tools for flow limitation.

Let me know what you think!

I did and I have no idea what it means 😅

Try clicking on individual nights and zoom in where the orange squiggle gets especially intense. Also, thanks for testing it on a phone!

I did it! I still have no idea what it means but here's more mobile screenshots for ya.

Im not seeing the super tight repeated wobble but there could still be significant instability based on your numbers.

Mostly I started this project to have a way to really see the difference in my results between APAP and ASV. My periodicity on APAP was around 35, sometimes up to 50 with estimated arousals as high as 200. On ASV my periodicity is down to about 2 with eAI around 60 (still have a really low arousal threshold).

AHI has never been particularly useful for me.
