Monthly trend in number of edits

Also shown is monthly trend for total reverts, for scale comparison

Chart shows absolute numbers (y axis scale shows number of edits relative (%) to busiest month)

Plot Edits

Monthly trend in revert activity, relative to edit volume

Per x edits, were anonymous edits reverted more often than edits by bots or by registered users?

Chart shows ratio reverts:edits per class of editors (registered or anonymous users or bots).
Note: often peaks in revert ratio in early years are not so significant as in later years:
low absolute edit counts easily led to high fluctuations in revert ratio.

Plot Reverts

Revert ratio is ratio reverts:edits per class of editors (registered or anonymous users or bots).
Only reverts detected by md5 matching are considered here, not (partial) manual reverts only detectable by edit comment.

Reverts is less than reverted edits! Sometimes several edits are undone with one revert.
Reverts broken down by number of reverted edits: 1 edit:87%, 2 edits:8%, 3 edits:2%, 4 edits:1%, 5 edits:0%, >5 edits:2%

When several revisions were reverted in one action, the oldest reverted revision determines editor class (and coloring):
is this a reverted user edit (reg/anon) or a reverted bot edit?

Monthly trend in revert activity towards anonymous edits

Are anonymous edits reverted often, and if so, by what type of reverter?

Chart shows absolute numbers (y axis scale shows number of edits relative (%) to busiest month)
Note: for many (not all) larger projects the not reverted edits show less seasonal fluctuation than the reverted edits

Plot Anons

'All anonymous edits' is same red line from first chart, scaled up vertically
Put succinctly: red - black = blue + brown + green
Only reverts detected by md5 matching are considered here, not (partial) manual reverts only detectable by edit comment.

Percentages are an approximation, as two simplifying assumptions have been made:
1) Anonymous edits are reverted only once (in other words edit wars on anon edits are not taken into account).
2) On each revert only one anonymous edit was undone. A frequency count of multiple revision reverts shows this is a simplification:
Reverts broken down by number of reverted edits: 1 edit:87%, 2 edits:8%, 3 edits:2%, 4 edits:1%, 5 edits:0%, >5 edits:2%

Distribution of reverts

Breakdown per namespace, type of reverted editor (registered or anonymous user or bot), type of reverter (same), was it a self revert or not, per time period.
Note: a high percentage in any segment can relate to a high absolute number of edits for that segment, or a high revert ratio, or both (please consult charts above for context)
.Projects pages are excluded due to enormous amount of false positives: some status pages are cleared often as normal process
