Well he is allowed to do ribbon cutting (with the ribbon being held by some means on the ground), so that gives you some idea of how low he can go. Incidentally it was during one of those ribbon cutting events that he had his one & only prang that I know of. He climbed out of that plane, got into another Pitts & calmly finished what he started! Lovely man - have had the pleasure of meeting him on numerous occasions over the years.
