He would not have been capable of even getting close to that kind of speed if he had used 100% of the leaf blowers thrust.
This is why I was surprised to see you make the statement that you did:
I am surprised by the amount that's harvested for actual propulsion....
Look at the amount of work done by taking note of the angle from the suspended hose. Dramatic difference, and this from a far more efficient form of thrust reversal. Put an obstruction between the cone and one side of nozzle to simulate the man's body impeding airflow to see how much that alone will hurt efficiency. Now use a less than ideal shape like an umbrella and see what little is left.
