Edge scrolling video is misleading

When I try to use edge scrolling as it is illustrated in the video, scrolling doesn't occur. To make it scroll I have to move my finger closer to the edge of the pad than is suggested in the video.
The width of the edge scroll area in the video is about 20% of the touchpad width. In reality it is narrower than that - more like 10%.
