Not exactly. There have been exceptions in the past, but typically they're adding HC girls to the HC CC, KH to the KH CC, and so on. Also there are three CCs rotating on a monthly basis and one new CC girl every two months in total, which means we're on a 3/2 (or 6/4) time signature. And they work in order, so now that they've just added a new KH girl for Chayotte (even though she isn't available for players as it's no longer Chayotte's month), the next one will be a HC girl for Chad in ear
