    • There were 642,559 Wikipedia edits amongst currently active users; this accounts for ~0.00009% of all edits on the English Wikipedia. (19:30, 15 November 2014 (UTC))
      • Of these, User:Juliancolton is the most prolific editor in terms of edit count (119,648), and ranks 208th amongst English Wikipedia editors. (19:30, 15 November 2014 (UTC))

Trends and Patterns[edit]

  • Winter Performance[nb 1] – WikiProject Tropical cyclones statistically performs better during the northern hemisphere winter months than during any other season; since December 2012, the project's relative Wikiwork dropped by 0.13 during the winter. By contrast, the project performs worst during the fall months, with a much lower drop of 0.037. This may be due to the prevalence of attention towards storms in the northern hemisphere, which tend to form from August to October and thus accounting for the lesser drop.
  • Hink Driven[nb 2] – The Tropical cyclones WikiProject averages a -0.022 Wikiwork drop on months in which Hurricanehink makes over 200 edits as opposed to -0.013 when this is not the case.
