+8.0 is an MVP season (think peak Dirk or peak Shaq) +10.0 is an all-time season (think peak Jordan or LeBron) (In the 2018-19 season, teams averaged around 100 possessions per 48 minute game.) A value of +5.0 means the team is 5 points per 100 possessions better with the player on the floor than with average production from another player.

In the extension, updated stats are highlighted with a yellow background as shown below.
When a game is live, stats are constantly updating but it’s difficult to follow exactly what has changed. If you’re interested in learning more about how possessions are calculated by various sites, Justin Willard has written about it extensively on Nylon Calculus.
