Hi Joseph,
Thanks for the clarification.
Any ideas why this number is much higher for some months? In particular, on
desktop, it's high in the months of July to September 2015 (around 10
million, compared to the usual 5 million) and then high again in October
2016 (45 million, about 10x the usual value).
Data is from
http://wikipediaviews.org/displayviewsformultiplemonths.php?page=-&allm…
which
summarizes results from the Wikimedia API (and stats.grok.se for data
before July 2015).
