During the control period, the user has limited control over speed and elevation. Within the initial
elevation climb segment up to 12 % grade, the users may vary elevation but not speed. Within the
other segments the user can vary speed but not elevation. The user’s selections are not persistent,
however. At the next 15-second mark, the controller as described above will generally choose a new
speed or elevation. The user is in fact advancing or retarding the action of the servo.
If at any time the Heart Rate signal is lost, the system will make no changes in load until such time
as the HR signal is regained. If the Heart Rate signal continues to be lost (no stable HR) for a time
period exceeding one minute, then start the cool down profile regardless of what the time period is.
