You've never flown aerobatics, have you?

I've only a couple of hours of aerobatic instruction.

Think combined spin and roll at high rate (greater than 300 degrees per
second). The forces exerted are dynamic, they are constantly changing
in direction and magnitude. In the spin, the nose is pitching up and
down while the yaw and roll components vary; the loss of a wing or
portion of a wing also impart their own yaw/pitch/roll components. The
amplitudes of each component are constantly varying.
