The great thing about this is that students focus more on their canopy flight during the first few jumps, without having to worry about the freefall. And in a day and age where injuries predominantly occur under canopy, this type of approach should definitely be considered by many more DZs. Both of these ratings are all about teaching, dispatching students, canopy flight observation, and debrief.
