Feature Request - Must have ability to ignore or undo last shot

Currently having to consider returning the unit as not fit for purpose.  1 in 5 shots do not register or register incorrectly even though all measures and advice taken to ensure proper placement of the device.  Virtual rounds and target practice are useless as several shots get incorrectly measured.  E.g. addressing the ball with my driver counted as an 11 yrd shot and I couldnt undo it.  The same goes for several scores in a round of target practice.

thanks
