 Announced rank average (Posted on 2022-02-16)
In some televised sports, such as downhill skiing, individual competitors take turns for the best time on a course. After each competitor the announcers will give the current standing. So for example, the first person will always be announced as ranked 1 (though this will likely change), the second person will be announced as either 1 or 2, and so on.

For an event with n competitors there will then be a sequence of announced ranks. What is the expected average of these ranks?

In long track speed skating, 2n competitors go on the same track but in pairs. So the first pair will get announced ranks of 1 and 2, the next pair will have two ranks from {1,2,3,4}, and so on.

For an event with n pairs, what's the expected average of the ranks?
