New Rating System ??????????

dwchang explained it pretty well in the site announcements thread

here's what i gathered:

Bayesian Average = (v/(v+m) x R + (m/(v+m) x C

(v/(v+m): increases -> 1 as you get more ops. Example: 8 ops = .53, 100 ops= .93, 500= .99

R: This is your "score," what would have been used under the old system

(m/(v+m): decreases -> 0 as you get more ops. Example 8 ops=.47, 100 ops=.066, 500 ops=.013

C: This is around 8, it won't change much.

Your Bayesian average is a sum of two parts.
(v/(v+m) x R can be thought as the "certainty of your score." Your video becomes more "certain" with more ops.
(m/(v+m) x C can be thought as the "uncertainty of your score." Your video becomes less "uncertain" with more ops.
As you get more ops, (v/(v+m) increases and (m/(v+m) decreases, so the bayesian average shifts towards R.
As you get a higher score, R increases, so the Bayesian average shifts towards a higher number.

I'm glad this new rating system was made. This way people will actually try and advertise their videos more often.

And Gene what are you complaining about? You do op. exchanges all the time. You should just focus on advertising your best video and do more op. exchanges just for that one.

Besides, it's supposed to be a list of the most popular videos. And that it is now, more so than ever before.

It's some of the small videos I find on the top 10% when they are first released and have 10 ops or so. So I download them and watch them and they are descent. So some of those videos go unreconized but your right advertising more is what I shall do.

Yes but gene, the alternative are videos that get on the top 10% and then are no longer downloadable so gain no more ops but stay on the top 10% without the chance of anyone being able to add any new opinions.

I find that reviews happen more through word of mouth than the top 10%.
