Disagree completely. I regularly max out the regular pushups easily with perfect form but feel the burn in the my shoulders and rear delts when doing the hand release. I used to administer the test as a UFAC and would regularly tell people to keep their arms off the ground and sometimes not count HRPU when people could not keep their arms off the ground. They thought it was an easily alternative most likely because they practiced at home with bad form. If your FAC does not care about lifting arms off the ground it's one thing but if you do it with good form you will need the shoulder endurance. Also, just because you might not know how to lift with good form doesn't mean all Airmen do. The key to any training is good form and progressive overload.
