Female teams are also hard to cast, because in general they don't last long.
Female teams like Brook & Claire, ok, but like Nat/Kat?? 
In general female teams don't last long on the race. There is no error at all in that statement. That doesn't mean that no female teams have, it just means that generally female teams don't last long.
In normal seasons 10 teams of women have made it2/3rd of the way through the race. Out of I think 39 all female teams. No the best results. Though since season 10 to current the numbers have improved, significantly.
