Switching off a breaker is not a reliable method to “trigger” Sense … when Sense is looking for patterns they are at a much higher sample rate than what we imagine as “on/off” … in those (normally) device triggered on/off cycles (vs a breaker switch) there’s a lot going on. Sense is likely to misinterpret breaker switching.
It seems like you are seeing evidence of the Sense brain getting smarter (in regard to your house) so I would try and keep things as “normal” as possible and let it do its thing!
Lazy wins!
