Reputation leagues offer at least approximate values showing how much reputation the users had at some point in the past. For example, I can check the reputation at the end of 2018, at the end of 2017, etc.
I am aware of the fact that the values in the reputation leagues are not exact values of the reputation the users had at that time. For example, reputation from deleted posts and reputation lost on downvotes (of answers) is not shown in the reputation leagues. Still, it is at least reasonable approximation.
At the moment, reputation is being recalculated networkwide from +5 to +10 for upvote on a question.
Question. Will this change be retroactive also for reputation league, or will past reputation leagues still show reputation calculated from +5 for questions?
