Been 9 years since I tested and It's nerve racking. One form has 100 moves and the other that I had to create, has 80. Then 6 or 7 fights and then 6 board breaks, 3 boards stacked on top of one another at each station. We use Number 2, pine shelving boards, 1x12's cut 10 inches long. Think that translates to about 450 to 500 PSI to break on average
