At the end of Learn Mode, the average bypass power is calculated.
From that point on, whenever the system is operated in Drive Mode, it keeps a
running total of the energy savings.
The energy savings is measured from a certain point in time. This starting point is
triggered by any of the following events:
Learn Mode is terminated
