if its possible with xara flash implementation, its good to vary the timing of the cycle and introduce squish - the rate of shape deformity and the rate of change of velocity [acceleration] should not be constant throughout the motion path, that's not what happens in nature - lots of stuff out in google about animation timing, including for bouncing balls - see attached - note the slowing down effect due to gravity and the effect acceleration/deacceleration has on distorting the shape...
