 For Method 1 and 3, you will notice that the angle between the virtual and kinetic foot segments does not change at the beginning/end of the trial. This is because the IK is only run between frames START+END, so at the beginning/end of the trial both foot segments are tracked using 6 degree of freedom, so they are the same.
