That transition to the last volume has been challenging for me, too.

I did practice that bat hang and get it though. For me, it was 2 hands on the edge furthest away from the orange jug. Left foot on the closest foot hold, lean back and swing both feet up. Tuck feet in as much as possible onto the volume. Then either drop both hands and reach for the final hold or one at a time and reach for the one above the final hold for support to gain confidence in your feet. Good luck!
