It was definitely 30+ cards when the specials started and for weeks after. I know because I was waiting for many cards following TRex's announcement and was thus closely watching the 9+ cards. All of Morgane's cards were rated 9+. Others included Diane Doll, Vicky S, Sandra H, Jana H, Lucky, Monica Scott, Jenny Gregg, Jana Cova, Ariel, Natali Blond and Stacy Silver.
I've discussed elsewhere the fake accounts and ***** used to drive down the 9+ cards and boost others. I wouldn't expect these people to change their ratings now just because the specials have finally been broadened.
Accounting for different tastes, I think the more members that own a card the more that card should sink towards an average. The average is probably in the 8 to 8.5 range.
I rate all the cards I have. If I get a card via subscription/specials and I don't like the girl/performance my rating can go to zero. This is not true when I pay 2 ticks for a girl I know I already like.
