If I go to my rep summary at https://stackoverflow.com/reputation, I can see this for today:
2 74322480 [10]
1 74322522 [15]
1 74317432 [15]
2 74317432 [0]
I know [0] probably means an upvote that didn't count (because I hit the upvote cap), but what does [15] mean? Above the previous entries were these, which have parentheses instead of brackets:
1 74318124 (15)
2 74318124 (10)
2 74319366 (10)
1 74319366 (15)
What's the difference between (15) and [15]?
As listed here, the third number is the amount of rep gained or lost. When you reach the rep cap, the number is wrapped in brackets instead of parentheses. Here's an example from my summary:
2 74310771 (10) 1
1 74308031 (15)
2 74308031 (10) 2

1 74322522 [15]
1 74317432 [15]
2 74317432 [0]
[15]and not like the other ones which are in parentheses(15)?
