Rolling surviving new active editors are non-bot editors who registered recently and saved a minimum threshold of edits in the previous time period and continue to be active in the current time period. Specifically, editors who registered between and days and saved at least edits in both time periods are classified.

Discussion[edit]

The n edits threshold[edit]

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 .

The u activity unit[edit]

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 .

Time lag[edit]

This metric has a built-in time lag of for the time period in question. However, new users who registered up to days ago may be included.

Bot filtering[edit]

Bots are filtered using the bot flag method.
