Tumescence Activity Units (TAU). This value is a time-intensity measurement that represents the
area under the tumescence curve above the baseline during qualied events. It is proportional to the
percent increase in tumescence over baseline. The Tumescence Activity Unit is calculated by summing
the tumescence value minus the baseline tumescence and dividing by 4 times the baseline. The value
4 is used in the calculation because there are four tumescence samples taken per minute.
