Yes I know that thread and also agree almost completely with aber, but I'm not talking about how wrong or illogical the formula is.
I'd like to better understand how does it work, for instance I remember recently someone said that there is no random at all in attendance calculation, so the only thing that could be the reason of the loss is the seat increase
Perhaps it's just a bug... maybe I should start from the bug forum instead! I'll try, see you there
