Accuracy of the o2ring compared to checkme

Accuracy of the o2ring compared to checkme
I own the o2 ring, but my hospital gave me the checkme for one night. So I had the opportunity to do a side by side comparison. I understand that the accuracy of the checkme will be higher as it reads every 1 second where as the o2 ring is every 4 seconds.

The checkme gave me a ODI of 2.4 for that night but the o2ring only have me 0.3. Checkme gave 21 dips whilst the o2 ring gave me 2.

Again, I get that it's a 4 second window and if a drop happened to fall within a four second window then it could completely miss it, fair enough. But to only get 2 out of 21 seems a bit much.

When I dig into the data and do a comparison of the tWo readings, I can see places where it could have picked up a drop where there is no way that it could just have missed it if it was taking every 4 seconds.

I have also compared it to a standard finger oximeter and I noticed the same thing. My oximeter dips lower than the o2ring does. It's almost like it smooths it over like the fit bit does with HR readings. 

Has anyone else noticed the same thing? I am considering returning it and switching it out for the checkme, but it could be that mine is faulty.
