I just checked my analytics recently, and I do agree with polokina that Top 10's count is much higher than Google Analytics for some reason.
Nevertheless, I believe that GA can most of the time distinguish and exclude hits made by bots (probably via User Agent detection).
I had an experience writing a server side counter and I was so surprised that most of the recorded hits actually came from bots, especially after a page gets shared to social networks such as Twitter.
So, if we want to find out why the count seems high, may be the best way to start is to log each hit's User Agent. This will be expensive but it can be enabled only in debug mode.
P.S. I don't use Jetpacks. I use W3 Total Cache.
