Something I thought of coming home from a birthday dinner this afternoon: In order to get a better idea of what the viewer is focusing on, you might consider going to a vertical gradient instead of a pointer heat-map. Most people don't read to the bottom of the page before they start scrolling. Imagine two lines on the screen- the bottom line is the point at which the viewer will begin to scroll. The top line is the point that the viewer wants their reading area to be located. The space in between the lines is your "target" area. As the viewer scrolls down the page, you could average their scrolling speed, and increment the intensity for that area of the heat map only when they slow their scrolling speed drastically, or go back over an area. Just from paying attention to my own scrolling habits, I think the top line would probably be just above the horizontal center of the screen, and the bottom line would probably be about an inch down. You could do some testing to find the average line positions.
