Can anyone clarify to me how does the Ranking system work? I don't understand it at all.

I have one image, currently with 4 rankings and 9 comments (Strange Moss), but I don't see it in the "best rankings" list, where it should be, I mean, near others with same number of rankings/comments. Not that I would die because of that, but I would like to understand how does it work.

In the page #20 (viewing 18 images per page) of the "best rankings" page, there are images with 4 rankings and 4 comments, so I thought that mine would probably be "higher" since it has more rankings and comments. Until the page #14, it didn't appear (maybe it's higher, who knows?). In this same page, there are images with also 4 rankings, but different number of comments, some bigger than mine, some smaller. In the very first line for example (I'm supposing that the "best ranked" are those who are listed first in the page), there is one image with 4 rankings/7 comments, followed by other that has 4 rankings/7 comments (with more views than the previous!), and another that has 4 rankings and 9 comments.

If my image is in higher pages than this one (it's not), why it is ranked better than the image with 9 rankings and 10 comments then? Strange.

I thought it should had some kind of order, like, images with 10 rankings and 10 comments should appear before images with 10 rankings and 9 comments for example (isn't it a bit obvious?), more or less like when it gets a comment, it would get one "point" or "credit", and the ranking would be based on the total number of "points" of an image. But this is not what happens. In the event of a tie, the number of viewings could be used, or something else.

I understand that the voting system is a different thing, if one image doesn't get voted, even having lots of viewings and/or comments, it won't appear in the "best voted" ranking (it's also very obvious).

I am not criticizing any image in particular, neither saying "mine are better", I just don't understand how the ranking system works, it's not as logical as it should be.
