The falls that were worrisome were L6-9 (Optionals). Like the L6 that flew over the bar on a clear hip and ended up (miraculously) catching the bar with one hand... or the level 9 that was doing an intentional release and her hands slipped and she landed flat on her stomach. i am checking my video to see if I have a clear shot of the bars.
Clear hip on the low bar or baby giant on the high bar? Sometimes kids just fall. It might have nothing to do with the bars.
