Here's why you're completely wrong. Your questions aren't relevant because you know nothing of the statistical behavior of the queue.
Consider two extreme cases:
(1) A million websites wait, neglected, in the queues. Meanwhile, every day a thousand new submittals come in and are immediately reviewed. Actual wait time for all 99.9% of all waiting sites, infinity.
(2) A million websites wait, and every day the oldest thousand websites are reviewed. Actual wait time for all waiting sites, under a year.
To a logical mind, the statistics you ask for can't distinguish between these two cases, or between any of the infinitude of possibilities between them.
A logical mind would have first asked which of those patterns editing reviews fall into. And ... it's somewhere between them, but nobody really knows what the pattern is.
So, unfortunately, even if you'd been logical enough to ask the right questions, you still couldn't have gotten any information....because it's just not known by anyone.
