This is very interesting.

Please have a look at the screenshot.

All of the cards in my 'demos' tab are those of Victoria Daniels.

This has never before happened.

Not a problem. Just interesting.

I will say that cards are becoming a lot less random in the 'demos' tab.
I now have nothing but Victoria Daniels. Earlier I had much of Candy Sweet. Before that I had much of Niky.

Anyone ever notice a 'demos' tab (when only five cards) full of cards of a single girl?

She looks really good in 'Satin Seduction' (on the far left in the pic) and 'Pumping Iron' (in front and center) where she is wonderfully barefoot.

I get this often. Mine seems to run in sequence and I get many of the same model in different outfits. I kinda like it, I get a good idea of what the girl is like that way.
The only downfall is that if you want variety that will not happen until the model change. However if you choose more girls then you are more likely to get a variety, sometime it works out to three girls with different outfits.

Okay.

I just bought two of those Victoria cards (above mentioned).
Immediately two cards of Naomi Nevena replace those cards.

I have recently noticed exactly the same thing .. not when having 5 cards but anyway I now have all cards of Dominio and all but 1 card of Mirca .. you are probably right .. they have changed the algorithm ..
