According to the stats, the last 12 months have seen a decline in overall page views by about 9-10%.

As far as I can tell these numbers do not include access to Wikipedia and sister projects through the API. And if I understand correctly, this means that e.g. access through the Wikipedia app is ignored.

Considering that mobile access through the browser is about 15-20% of the overall access (if I read the graphs correctly), is it possible that the current page view numbers are underreported?

If a reasonable portion of mobile users use the app instead of the browser, then these numbers should somehow be included in the page view statistics, or wrong conclusions might be drawn.

Any ideas?
