Rolling new active editors are non-bot editors who registered recently and saved a minimum threshold of edits. Specifically, editors who registered within $u$ days and saved at least $n$ edits are classified. Note that rolling new active editors have the potential to be counted as rolling surviving new active editors if they continue to be active more than $u$ days after their registration.

Discussion

The n edits threshold

The edits necessary to cross this threshold, the fewer editors will meet the criteria. Historically, "active editors" were considered to be editors who made 5 edits to specific types of pages over the course of a calendar month. So for historical purposes, we recommend $n = 5$ .

The u activity unit

The wider this unit is set, the more casually editors will be considered "active". Historically, "active editors" were considered during calendar months. So for historical purposes, we recommend $u = 30$ .

Time lag

This metric has a built-in time lag of $u$ .

Bot filtering

Bots are filtered using the bot flag method.
