I recently asked this question on Meta
Close Vote review queue 40 or 20?
Regarding why on some days I have been able to review 40 close reviews but on others only 20 and received the answer that the queue was dynamic and that if the length of the review queue was more than 1000 the number of reviews we are each allowed is increased to 40.
Is this threshold something that can be changed and if it is can and should we be reducing the threshold to a level where we can gradually reduce the queue to the point where we can eventually reach the point where on average we can between us clear the Close review queue each day.
I would not be in favour of allowing more than 40 votes as to properly review questions takes time and effort. We certainly don't want people to review on auto-pilot blindly closing everything or leaving everything open. Nor do I want to burn people out.
However, at the moment the close queue is too long and bad questions and answers are taking too long to be closed
