An example of an alternative method is what Spaceland has done recently. They have a WS waiver and some mandatory oversight of the WS training.
Elsinore has had a program for some time.
But not all DZs have a training program and some DZOs are not aware of all the issues involved in WSing. One of the most overlooked issue in the WS flight path and how it may interfere with other jumpers, GA and/or ATC requirements.
