Countering active admin flight
This graph is a waste of time for our task force. It shows the number of admins is declining. It's unclear what this has to do with quality. Instead, a graph showing the number of admin actions vs. the amount of needed admin actions would show us something. Sadly, we haven't got such a graph.
This is why I treated users, edits and edit rates separately in my essay. Using the wrong thing to show something is an unwanted form of data manipulation.
The number of admins is declining while the number of editors continues to climb. Is there any reason that doesn't have negative implications for the amount of admin actions versus the amount needed?
There is no reason to assume it does. You are comparing apples with pears.
It seems to me you are claiming that the number of necessary admin actions does not vary in proportion to the number of editors. There is a strong argument from induction that it does. Do you have any evidence that the correlation is zero or negative?
Why should I spend time proving a negative? Come up with data about admin actions, and we have something to talk about - well, even then the need for such actions may have decreased too.
