This must have been asked before, but I can't find it.
On this page (and similar others), how exactly is the first column (which shows the tip "total score") computed? My question apples to the "answerers" and "askers" sections; and to "last 30 days" / "all time".
For instance: for answerers, last 30 days, the number is too low to correspond to reputation earned in the last 30 days; and too large to be average reputation per day in the last 30 days. So what is it?
