I'm lost in understanding the 28-day window for core web vitals.
When did the 28-day collection period start for CWV?
Then, if a site has fluctuations on a metric between the 28-day window. For example, LCP day 28 - 2sec then day 24 - 4secs. then day 10 - 1 sec. Means the window will start again?
Is it possible to activate a new cycle for the 28-day? And how?
How we can calculate the improvements of the new 28-day cycle? Like a table breakdown per day?
