Hi Jerry-

This is how we have been using the VRC16 template supplied by Dec.

1. Place template on VRC16 screen
2. Push template to very top of screen
3. Using the lower top red line
4. Line up top line and bottom line so it looks 
   like one line
5. Count number of pixels above the red line in
   the middle to give middle count
6. Without moving head count pixels above the 
   top lower red line on right or left depending
   which side is the worst
7. Subtract middle count from right/left count
   and this gives the difference in pixels above
   the upper lower red line from the right/left
   to middle
