In the past there have been plans that provide for a Program with less calls (ABC, Community Dance Program, Basic 1, etc.) with little thought to moving those folks who dance that Program forward. There have also been multi-cycle plans which have short periods between new class starts but they have not included a way for people who want to, to dance frequently to a Program lower than Mainstream.
The plan described here is a combination of the best parts of those two plans, and shows that if it is implemented in a region where there are multiple clubs, who all follow the plan, a new dance Program can be introduced into the region which has fewer calls thus creating a pool of dancers from which new Mainstream dancers will eventually emerge.
