There are quite a few questions here.
(1) Your page-views are down x % is based on the previous week/months views. i.e. if you had 100 page views last month and only 40 page views this month then your figures would show a drop of 60%.
The opposite is true for your profile views. 25% more people looked at your profile page.
So if 100 looked at it last month, then this month 125 people looked at it.
Your unpublished hubs page views are from your editing activity on the pages.
Finally the default setting is to follow all hubs you comment on.
The little check box in the bottom left hand corner of the comments box must be unticked to unfollow.
Hope this answers your questions Phew! lol
