How accurate and up-to-date is the Active installations chart?

We released a new version of our APP (1.1.5-AC) and we know that most if not all our clients have upgraded to the new version. However on the “Active installations” chart, it shows not client on the latest version.
I understand the chat is updated once of week on the Monday. Today is 8th June and the chat shows from 2020-03-03 to 2020-06-01. Does it mean on Monday is show data till 7 days before? It is confusing.
