OK, I am not sure I understand the issue correctly, so I'll just throw out some notes:
* I do not count the pageviews. They are counted by the Wikimedia Foundation, I just use them as-is.
* The official definition of page views seems to be at
https://wikitech.wikimedia.org/wiki/Analytics/Pageviews* AFAIK, the data before 2015-12 used only desktop views; the new one uses also mobile, but removes "views" by bots and crawlers.
* Not sure what the "bounce" feature is; the preview thing in the mobile app? Or the MediaViewer? (I believe page views count neither of those)
Finally, a "view" in the baglama2 tool means an image was included on a page that a human loaded in his/her browser. I have no data if that image was actually on the screen ("below the fold", no scrolling), but since "important" images in an article tend to be near the top, I just count the page view.
Hope that helps,
Magnus
