There's another CAP 69something for Performance (I'm helicopter so didn't need it). I believe they are all downloadable.
One thing we found useful in order to read the graphs in these manuals were strips. Simply made from overhead transparency plastic, cut into a long inch-wide strip with a straight line (in contrasting colour e.g. red, green etc) ruled on it with permanent pen.
Use these on the graphs to avoid pencil marks when you're reading off the graphs.
