- the present embodiment adopts both min values. That is, after calculating both the start completion progress based on (1) and the start completion progress based on (2), the smaller value of both (progress) is displayed on gauge G . According to this, it is avoided that a higher degree of progress than actual based on one calculation method is displayed.
- notification is made by a display display.
