How does the rating system work?

Forgive me for probably sounding quite stupid, but can someone explain the rating system? Or link me to somewhere that can?

I've probably missed it somehow, apologies if this is a rampantly stupid question.

Thanks in advance!

Please read the site FAQ.

Ah, got it.

It just seemed a little erratic, but I'm clear now.

Cheers!
