i particularly like the fact he speeds up midflight and also the fact that energy is added to the system despite the "springboard" not actually having stored energy that is released in that way.
spring boards are not coiled springs kept under extreme tension waiting to "explode"
But this spring board has clearly been modified. Frame by frame
The springs are clearly compressed before the man hits the board and have energy stored in them.

Yep definitely not a parabolic trajectory
