My take is what I might call “last session statistics”. The “latest” time is there - the min, hr, days ago column.
But there is nothing about what they did during that particular visit. For example, columns for someone that logged in, checked a topic for a reply, and then left, compared to another that read a bunch, posted a few, liked, etc. show no distinction.
AFAIK, data this granular is not currently easily possible for most data and would require at least another table. A table that in my estimation would be massive.
I have been working on a script that uses exported data and tables of monthly “snapshots” so that I can use JOINS to graph monthly changes and it is an extremely resource intensive script.
My suggestion is that if any steps in this direction are taken it be only slightly more granular than cumulative. “session stats” feel like a no-go. Though the data would be interesting and most likely helpful, I’m not convinced the cost would be worth it.
On the other hand, there are tables that can be queried when this kind of member-level information is desired. I just can’t see it as an “always displayed for everyone” feature.
