Last April, 2016, I competed in a Grade 4 Adult (EUSPBA) event at the highland games in Dunedin, Florida, a true hotbed of piping in the Southeast United States. It had been raining heavily all morning, and I was due up in a large group for the 2/4 march competition, with Rab Mathieson as the judge.
Things go wrong. It is our condition as humans. We aren't machines that execute tasks perfectly every time. In piping, we have a multitude of variables to which we need to attend in order to have a successful performance. Some of those variables, such as the temperature and the relative humidity, our out of our control.
