Unfortunately the tag wiki for reference-request isn't very helpful. How "specific" is the query here? The question reads as if the OP is looking for a few lines in a literature search on a topic. Whether the topic has to do with academia or not is, to me, irrelevant. The question seems to be trying to avoid closure for being "opinion based" the earlier one was. However, the question isn't based on a problem that someone in academia has. Answers will solve no problem.
A good question (or answer) on this site is, IMO, one that a reader can return to in three years and say "Yes, I can use that.". That isn't the case at all here unless you are researching a specific topic and need that lit search.
The question at hand, and sadly others on the current active list, are without such consequence or future usability. On learning that the "average" academic spends, say, three hours per week doing reviewing, my response would be (a) "That's interesting." and (b) "So what?". The standard deviation of such a result would be so large as to make any "average" meaningless. For myself, I either don't do any reviewing at all for months on end, or do it extensively for many hours over the course of a month depending on conference scheduling. But that is about the specifics of this question, not the general situation.
The help center says: "You should only ask practical, answerable questions based on actual problems that you face." I don't see any problem here other than a specific research question.
I still think it should be closed.
About the tag itself.
If I write a question of the form "I once saw some research on the significance about Mumbly-Peg among pre teen boys, but lost the reference. Can you help?", it would be a valid reference-request. If I ask for "I'm interested in the significance of Mumbly-Peg among pre teen boys. Is there research on that?" it would be, in my view something else. Specifically, it would read like asking others to do my research for me.
