If it was an auto from 500 AGL starting at zero airspeed with a 360, you were playing with fire.
Rate of descent in that maneuver in an R-22 well exceeds 2000 fpm ROD. Not smart. Had a CFI demonstrate that one a few times with me onboard back when I was clueless, and he almost lost it on the last attempt. Pointless cowboy flying. Not recommended
