The base line readings are printed on the photo that shows the car on the table. You would use those numbers against the numbers next to the picture of the part being changed/substituded. As an example, the F104 pictured in my post has the baseline numbers:
BASE LINE
Center Wind Pressure 52.0
Total Drag: 101.3
Total Downforce 83.3
Front Downforce 40.0
Rear Downforce 43.3
CHANGE
On the next page they show the rear wing on the body (not the rear wing itself) being trimmed out. The result is:
Center Wind Pressure 55.1
Total Drag: 98.3
Total Downforce 79.8
Front Downforce 35.8
Rear Downforce 44.0
AFFECT
Total difference by changing that one thing is:
---------------------------

I hopes this helps.
