I think you're right for #67, but #22 is correct in the book. "Normal" would be your approved takeoff flap settings (10 or 20 degrees in the 747-200). You are correct about the difference between 10 and 20 degrees. However, in most "heavy jets" an increase in takeoff flaps beyond (again in the 742, 25 or 30) that results in significantly increased drag and a huge hit in acceleration. Very similar to the reason for setting flaps to 20 degrees immediately on a go-around.
