After watching the video of his exit, it seems that exit was normal. Not the greatest push, maybe a bit to the side. He pulled straight after exit, with no delay then a 180 cliff strike to the ground, cliff strike to the ground.
Looking at his positive side
He was a Positive person
Good decision maker despite the experience level
Experienced Paraglider Pilot
180 Resolution skills

His Negative traits
due to the positive points mentioned before
His own Complacency due to bad group dynamics during a Base boogie
a winter without jumping
second slider down stowed from a cliff
not really a cliff for slider down (500m, slightly overhanging, too much cliff to the ground in case of a strike.)
Report and information has been written by his Mentor
