The switch on our board is pretty cheap and it de-bounces. For example, when I tried pushing the button with the tip of my nails then it showed jumps of two, but when I pressed it with the flesh of the tip of my finger then it showed jumps of 1. So, our button can show more than one jump when pressed in certain ways. If you are getting one or two extra jumps then don’t worry. If your count is off by hundreds or thousands, then there is a problem with your code.
