I'm interested in running 100% on PS5 but I can't understand the category rules. If someone could explain them to me in a simpler way that would be nice

Complete 100% of the district map screen (all collectibles, side quests/phone app quests, all main missions, etc).

Then minus the time stated in the rules from the final time for your actual time as we time this game without the unskippable cutscenes due to patches adding more in later patches.
