Until very recently (yesterday or this morning UK time), when you mouse over the reputation change score of a given user on the Users pageUsers page, you got to see the precise reputation change for the selected period.
The pages themselves show rounded values for larger reputation changes (anything over 10k). For example, Jon Skeet got roughly 101k reputation so far this year. The tooltip on the '101k' would show you how much exactly he gained this year.
Not so anymore today:
Now (at rev 2013.11.4.1115) we just get the rather meaningless 'reputation score' text, which surely cannot be intentional. Can we have the exact values back please?
Note, the 'all time' page doesn't suffer from this problem, the other pages do.
