I'm not experienced on the points for a AKV standard studio yet, but if there is a difference in points between that and the BWV standard studio, you would have to pay more or get a refund from the owner. And then the owner might be stuck with points that he/she can't use at that late date.
If it takes more points, you would probably owe more.
If it take fewer points, the member could wind up with left over points that couldn't be used.
