Change in the breathing rate algorithm?

Hello - tonight we received the update to the new auto-detect feature for breathing wear. We're excited about the feature... but it's also coincided with a large increase in my daughter's breathing rate.

Background: Typically her breaths per minute hover between 19-24 breaths per minute (when she is healthy), and it's only when she's very feverish that it climbs above 30+ BPM. W

Tonight - we turned on this new feature and instantly her breathing rate is at 33-34 breaths per minute. We know that it's possible that the historical breathing rate could have been low, but also has remained very very consistent over the past 12 months.
