I want to post a link to Saladino’s 8.73 jump from an interesting angle, it’s actually a “flat” jump. There’s a lot of people getting same lift off the board yet jumping way less than him.
This angle, side view and observer height, shows that he doesn´t get that much of a lift as awaited in such an enormous jump.

The faster the jump the flatter the trajectory will look, but it’s deceiving as the change in his hip height from the ground was huge (at least 30+ inches).
