  * The next two functions overwrite the behavior of the stock functions and do not perform equivalently, except

  *
  * The stock implementation of GetTransmitterScore (which I cannot override) is:
  * Score = (1 + DataResourceCost) / DataRate
  *
  * The stock DataRate and DataResourceCost are:
  * DataRate = packetSize / packetInterval
  * DataResourceCost = packetResourceCost / packetSize
  *
  * So, the resulting score is essentially in terms of joules per byte per baud. Rearranging that a bit, it
  * could also look like joule-seconds per byte per byte, or newton-meter-seconds per byte per byte. Either way,
  * that metric is not a very reasonable one.
  *
  * Two metrics that might make more sense are joules per byte or joules per byte per second. The latter case
  * would look like:
  * DataRate = packetSize / packetInterval
  * DataResourceCost = packetResourceCost
  *
  * The former case, which I've chosen to implement below, is:
  * DataRate = packetSize
  * DataResourceCost = packetResourceCost
  *
  * So... hopefully that doesn't screw with anything else.
