Calculation of standard deviation of mean velocity (#643)
Calculation of standard deviation of mean velocity (#643)

I guess this should be the standard deviation of the average velocities of each run?
In the visualizer_rrlib_py, the same calculation is done as:

 print('Average, std speed: {}, {}'.format(
        np.mean(mean_speed), np.std(mean_speed)))


Maybe, on top of this, they could all share the same result evaluation methods.
