You`re absolutly right. This wall is about 250 meters with possible delays 5-9 seconds (depends on tracking), and 2 years ago i made double frontflip there without any problems, and yes, i initiated the rotation straight after the exit. For myself that was enough for 2 flips in 1.5-2 seconds.
But the main problem is that most of all new russian basejumpers forgot that base is dangerous and that even the simpliest aerials in base still require at least one acrobatic taining
