Does the best distance beween 2 spokes match the inverse RF wavelength ?

The spoke pair k-space trajectory is known to be efficient to compensate for B1 inhomogenity in tailored slice selection at ultra high field. In the Magnitude Least Squares problem, the parameter of interest is the distance between the 2 spokes. The optimal distance is analysed across different human brains and slices at 7T. It seems to be fairly constant and its inverse is shown to roughly match the RF wavelength in the human brain.
