getOxygenSaturationHistory on device

Here description, picture in next post.

1. f6p 22.10 (last firmware) CIQ 3.3.1, WHR 5.00.05, sensor hub 18.02

2. sdk 4.1.4/win/eclipse

3. on sim everything looks ok

4. on device - very, very poor

- why iterator's  getOldestSampleTime is different from the oldest sample (sample is older)

- why most samples (99.65%) are bad (null, or data not between 0 and 100)?

- why system saves data (and consumes a lot of energy) into history (of course bad data) when I switch off sensor in watch settings (I've done it about 6/15 19:00 and can see samples at 6/16 01:20)
