Squawk,
I think you
might be barking up the wrong tree.
An aircraft such as the one flown in this instance can climb rapidly with a
gentle application of elevator at cruise speed and conversely with
gentle application of forward elevator the aircraft could easily progress into a negative G situation. As long as the aircraft G limits are not exceeded I cannot see how this could be deemed as aerobatic, not smart,
but not aerobatic.
Please recheck your facts with your CFI.
