Plot delta y for hinge and show how hinge traj is changed by the opt - phase shift?

Red old blue new

ret2 = @time opt1(m, ret1["traj"], ret1["param"], 1, 180; Φ=90, Qdt=5e4)

120 deg

minal 400, 90 deg

120 deg

Not very conclusive, but could argue that

• the hinge amplitude is changed
• phase is changed very slightly

Need to write this section - any point? Just to demonstrate how delta y works
