Picked this up from Tim W's play by play topic.
"Low pullouts inverted are when you knock the vertical stabilizer off your Ringmaster.

Anything lower qualifies as a crash. Layingdown

My long time flying buddy, Gil Reedy, told me about watching Steve Wooley, an early great stunter, do the pattern. According to Gil, on the outside squares he hit the first one too low and dragged the rudder across the bottom, did the same thing one the second one. Technically not the best, but very impressive.
I watched an old friend, Jeff Welliver, pull out upside down on the RWO, dragging the tail. He kept it there until enough of the rudder ground off that he could pull it off the ground and completed the maneuver. At least he was as level as possible for that half lap.
