Quite a bit actually. Mostly that reporting is only available to "some" browsers (the majority but not all) but also only the main document is counted and a pageview is more than the request of the main document. For example, you will not get all 301s/302s or images and there are many, many other details. 

See pageview definition: https://meta.wikimedia.org/wiki/Research:Page_view

The good source for Recent pageview data is hadoop, going back a bit the well-loved webstatscollector files provide that info:

Navigation timing is heavily sampled so I am not sure you could estimate pageviews with the scarce dataset it provides, I would say it is not possible.

It uses 1:1000 random sampling, so I have to count the log events and multiply by 1000 to get a good estimation. Am I missing something?
