Ha, ha, HA! That's awesome!
I would've considered carbon to fail as soon as the first crackle because that indicates individual fibers/resin disbonding. Everything beyond that is a matter of degree. Catastrophic failure after that requires a duty cycle & time components. Nevertheless, the rider would've lived to fail at jumping again, & again, & again. The aluminum riders attempts at failing to jump would be much more limited.
Cool stuff.
You know how Boeing has wing failure test videos for all it's planes?
777 as an example.
It doesn't have one for the carbon winged 787.
Oh, they have videos of them doing the test.
They don't have videos of it failing.
You know why that is? They couldn't do it.
They failed at fail testing.
The testing rig didn't have enough travel to deflect the wings to failure.
It deflected the wings until they couldn't go anymore and that was that.
Carbon is cool stuff.
