One of my favorite parts of these types of simulations is seeing what bizarre movement it converged on when the cost function ends up being 10x lower than I anticipated.

My last unusual result came with a big lesson: "double-check if the time length of the .trc files is equal to your time-bound"

I accidentally asked the model to solve the problem, in which the markers stopped immediately and stayed there still for half a second. It was the biggest backward jump that I ever saw on a computer (fast braking).
