Yeah, I have definitely seen an evolution, shall we say, in their modeling and data aggregation and smoothing. Oura is doing a public "beta" of a new sleep mode

Yeah, I have definitely seen an evolution, shall we say, in their modeling and data aggregation and smoothing. Oura is doing a public "beta" of a new sleep model now and it is VERY different! But much better. So it goes. There are also inherent power limitations in the ring form factor compared to the watch, which impact data granularity. If you want to be monitoring apnea you really need seconds level resolution, and Oura is tens of seconds. Anyway, agree about limitations. It has still been very useful for me! Cheers.
