It did have 0 eariler Marioh
From what I can tell, it takes the members that aren't the Club organizer and rounds down to the nearest dollar, then sums it up.
Of course that doesn't explain BB's club, unless he has a member coming in and just hasn't shown up yet??
edit... ok that 1158 is exactly what he has won in credits since forming the club. Doesn't count the owner's credits before the inception of the club, but does after? Ugh, have to think that is a bug.
