getAveragedDuration method

Implementation

double getAveragedDuration(){
  for (int i = partialTimes.length - 1; i > 0; i--) {
    partialTimes[i] = partialTimes[i] - partialTimes[i - 1];
  }
  double result = partialTimes.reduce((a, b) => a + b) / partialTimes.length; //Media aritmetica
  return result;
}
