The graph i plotted is velocity of movement across the stroke and nothing else !
Now that I'm aware of this i have some doubt in its abiliity for flight
it may be more useful in water were symmetry and a curved path is good !
Sometimes it is difficult to make and measure mechanical movements if you donít have the proper instrument.
