Your Mood KPI is a rolling average.
It is calculated using all your pulses from your last 30 days.
So the result from 31 days ago, will be replaced by yesterday's result.
Imagine if 31 days ago you had unusual green results for example. This day will now be excluded from the Mood KPI and replaced by another day results that is neutral (as no one was pressing that day).
This way you might get a minimal change in your Mood KPI on a day when no one is working / pressing, like on May 26th.
