So, the acceleration in the jump to hyperspace would be a g-force of 3,461 g's. That's a large enough acceleration to easily squish a human if you don't have something like an inertial damper. But ...

Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

He doesn't jump very high, but his acceleration can be super high (around 30 m/s 2). I guess he is using the Force during his jumps to make him get back down to the ground faster than normal.
