There are two (possibly three) ways to review suggested edits:
- via the review queues
- by visiting a Q&A page where the edit was made, and clicking on the
edit (1)
link underneath a post - authors of a post get an inbox notification when a suggested edit is made; however, clicking that link redirects you to the review item itself, inside the review queues (1.)
Is there anything known about the number of reviews made via 1. and 2.? Mainly because I'm curious, but it could also help in determining ways to improve reviewing. As they say in the Netherlands, meten is weten (to measure is to know; in Dutch it rhymes nicely). It's likely that it's not directly stored in the database, but perhaps it can combined with page views?
I wrote a SEDE query to check how many edits were reviewed by post owners (about 16% here, on Stack Overflow and Mathematics; other sites like Super User and Ask Different have single-digit percentages). Interesting, but not really what I'm looking for.
