While I live in Canada where everyone gets individual routines, I can begin to imagine how it might be. At my gym the floor routines in the interclub (older, lower level competitive)program are often recycled for years on end. There was one routine that had 4 gymnasts doing it for the first 2 years that it was used (it has driven me insane since the first year), and then didn't get retired for about 8 years. Although there is another routine that has been around for almost as long that I still like, but it never had more than 2 gymnasts doing it at once.
