Large time gaps between votes in the Review Reopen Queue

Question

Questions in the Reopen queue don't last for more than a minute, so I'm curious, how is there such a large time span between the second-to-last vote and the last vote?

In the first example, at the time I'm posting this, there is a 17 minute gap between votes, and in the second example, there is at least a 30 minute gap between votes.

Here's a real weird one:

The second-to-last vote was on Feb 7 at 13:39, and the last vote was yesterday?

Is this just a case of leaving a browser tab open and coming back to the tab later, taking great pains to make sure the question needs to be re-opened or not, or is it something else?

Answer 1

The reviewer in these cases seems to have left the tab open and then come back to review it after the item was already reviewed to completion. (We record "review duration" on our end, and he spent ~20 minutes on each of these reviews.) This may have been done to exceed the daily review limit.

In general, we give everyone credit for a review, even if the item has already been completed. To prevent behavior like this, though, we'll add new logic to not count reviews that took over two [edit:] 15 minutes if the review item has already been completed.
