How difficult, Jeb Corliss wing suit stunt?

To the original question: Not that difficult, mentally stressful far
beyond anything you will do in a glider and of course unforgiving of
small mistakes. Anybody fit, aggressive, and with reasonable aptitude
could give it a go after a few seasons jumping every weekend(provided
they were training for this as a goal.) There have been about a half
dozen wingsuit proximity deaths in the last few years, no idea how
many people are playing the game. If anyone wants to try understand
it takes a tremendous amount of time(money helps) to travel to these
places, learn lines, hike, wait weather, etc. Similar to racing
sailplanes, you can't do it if you only have 2 weeks vacation a year.
As the saying goes: Good pilots don't have real jobs...

Mainly curious about how difficult that was.
Thanks.
