Choose your tier and set your base — head and hands in a stable tripod, or forearms for that tier. Walk your feet in, lift into the headstand for your tier, and hold as long as you can. Come down under control.

Declare your tier before starting. Timer starts when your feet are up in the declared position and stops when they come down or the wall/support rules for your tier are broken. Use a mat. Longest hold at your tier wins; a higher tier always outranks a lower one.
