//NOTE: The reason "average" is quoted is because it is not a true mathematical average. This is because I have
// found what I call a "sequenced average" is more successful in execution than a real average. The difference
// is that the sequenced average doesn't use the pool of all values recorded thus far, but rather averages the
// last average and the current value received (in sequence). Concretely:
//
// True average: (1 + 2 + 3) / 3 = 2
// Sequenced: (1 + 2) / 2 = 1.5 --> (1.5 + 3) / 2 = 2.25 (if 1, 2, 3 was the order the values were received)
//
// All "averages" in the program operate this way. The difference is subtle, but the reason is that sequenced
// averages are more adaptive to changes in the overall volume. In other words, if you went from loud to quiet,
// the sequenced average is more likely to show an accurate and proportional adjustment more fluently.
