Google Takeout Fitbit Data of SpO2 by the minute on Pixel 2

Hi everyone. I am able to get the average O2 readings on my watch after a night of sleep. I also understand it does not spot check. However, when I get the google Takeout dump by downloading my own data, and I go to the fitbit-->oxygen saturation folder, I see a spreadsheet. The spreadsheet has a by-the-minute reporting of SpO2. Many of these readings are noted as '50'. What does this 50 mean? Is it really getting minute-by-minute data? Do the times line up with real life? Will we ever got spot oxygen checks?

I'm wondering the exact same thing. I just was looking at the SpO2 data and I'm wondering what all the 50s are. I'm guessing they're invalid reads or something since on the sheet with daily summaries, they don't seem to be factored into the average and aren't included as the "lower bound," but I'd like to know for sure. I couldn't find documentation about this anywhere (including the readme docs included in the export).

I am still waiting for a reply to this. Inquiries to google have said to contact fitbit. Can I bump this?
