Since the likelihood that the ball just hits the racquet longitude axis is almost zero, thus according to your data 50% of ball contacts would be above middle line and 50% below. So, your data also demonstrate that players don’t have tendency hitting the ball below middle line.:
Some of my pictures (1, 4, 7, 10) show impact below middle line.
