The definition states that "Centers of each side Cast Off 3/4 as others do their part of Fan The Top." Later, you note that "Note: The Cast Off 3/4 is sometimes a 'Push Cast.'"

If it is a Push Cast, who does the pushing? I was taught that when in a couple, a Cast Off 3/4 means it's a push cast, with the center pushes (or, as the Mainstream Callerlab definitions note, the end dancer becomes the pivot point). In this case both dancers are centers. Based on the definition of Trail Chain Thru on the same page, I'm assuming that it's the dancer closest to the center of the set that pushes, but I'd like confirmation of this.

Also, can the movement "Centers of each side Cast Off 3/4 as others do their part of Fan The Top." be described as "Any-hand Fan The Top"?
