what kind of black sorcery is this?

how did you get a fs hippie flip and a bs hippie flip? Plus all the other hippie flip madness. You found some magic formula. Go at the rail sideways and the rail has to be slanted downward or upward.
This is a master class. How long did each one take? I see the last one took three tries, but how long did the first one take? Saunders, dude, wow.
