Even that doesn't totally make sense because you have to have least "post" your score of 5 or lower for it to count not everyone that owns a card are posting, (unless i'm missing another way to vote) and that still doesn't account for new cards/girls
You need to take 2 things into account:
1) People who purchased the advent calendar subscription are "*****" to own a girl they normally would not have bought.
2) Human behaviour. It is a well known fact that people are more likely to ***** when recieving something they disaprove off, rather than the likelyness of honouring the good.
Due to the subscription there are more owners of a "bad card".
