I do not understand how popularity mechanism works. For example when I fetch popular persons I see that Thai actor Thassapak Hsu is on top . When I see he has the popularity of 135 while Brad Pitt is only 28 and I said wow, How can that happen ? what is the logic behind this ? And I also see average popularity for directors are around 10, are they using same range ?

And I also noticed most person has popularity of 0.6, is that minimal/default value of the popularity ?

And another question, there is voted_count, is that count for popularity index ?
