Weighted average, again.

Ok. Could somebody please, once and for all, in a clear manner describe how the weighted average ranking system works, and what is the reason for using it?

I Code with My Sunglasses at Night 100%

Four votes @ 5, and one vote @ 7, yields a weighted average of 6.2... Why is that good?

Also it's OTTER CRAP.

But seriously, why is this system neither explained, nor fixed? Why not just have it so that one vote = one vote?

Actually, it _was_ explained. When all (or at least most of) the releases/sceners reach a certain (high) amount of votes, the system will start to work. So, CSDb will have a more or less objective chart in a couple of years. Till then, just try get used to it.

Yeah, I read some supposed explanation of it, but it was certainly not comprehensible, nor did it provide any reason for using this statistical atrocity instead of a normal mean average and letting every vote be of equal value. (Yes, I realize there are "downvoters", but the solution for this problem is not having the average rating formula try and figure out which votes are "real" - that's for a psychologist to do.)

Also many entries may never receive more than 10, 11, or even 5 votes, in which case the "wait a couple of decades and all will be fine" argument is lost.
