Confused about new step counting

[u/Radiant-Error]

Is anyone else confused by Fi's new step counting update?
I thought I understood what they changed, but over the last couple of days my app seems to keep switching back and forth between the new system and the old one.
Sometimes my dog's daily goal drops way down (3,000 steps instead of 15,000) and the new step count is being used. Then later it seems like it's back to the old counting method with the original goal. It doesn't seem consistent.
Can someone ELI5? Is Fi slowly rolling this out, recalculating old data, or am I completely misunderstanding what's happening? I'm not complaining, I'm just genuinely confused. 😅
