I was rating a skin via my new homepage, which if I had gone thru the normal channels I would have given a 9 to. However, as there are only 5 stars in all, and it wasn't quite a perfect 10, I decided to click on the 4 star rating. Later on I was checking out the same skin, but this time via the normal WC library and I saw that I had apparently rated it a 7, which was certainly not indicative of my opinion.
So I decided to go thru all the stars and see what each one translated as:
5 stars=10
4 stars=7
3 stars=5
2 stars=3
1 star=1
it seems, if I use the star sytem to rate, I can either rate something that's pretty-darn-good-but-not-quite-perfect a 10... or a 7.
personally I'd like to keep the marks out of 10 system as it gives a broader choice, but failing that...well, I'm not sure, but the tarif as detailed above seems flawed to me.
