For each poll cycle that does not receive a response for one or more poll messages, the barometer will increase by two (2), with a maximum value of 100. For each poll cycle that does receive a valid response for all poll messages, the barometer to decreases by 1, with the lowest value being 0. These barometer changes cause failures in communications to show up quickly as the barometer rises. However, good communications must be maintained longer and more steadily for the barometer to fall back to 0.
