I think
Its based upon the number of people that view and click like.
So if 5 view and one like, you get 20%.
Can't be that, but it's something similar:
52.6 Rating
32 Views
3 Votes
I liked/voted and it went up from 47 at 2 votes to what you see above.
I would assume it comes from the number of likes?
It does seem to be related, just not sure how? Maybe each vote increases the rating by a set, diminishing returns amount?
