Mark,
Your chart makes sense when I read it, and your obviously more versed on this subject than I. But take a car for example;
engine has 500 ft lbs of torque and run it through a torque converter which multplies it by 2.5 resulting in 1250 ft lbs of torque. Then through the transmission with a ratio of 1.90 and now your up to 2375 ft lbs of torque. Now run it through the rear end with a ratio of say 4.88 and your torque is now 11,590 ft lbs of torque at the tires. Your initial 500 lbs of torque becomes almost 12000. Your right that torque is torque, but the book I am reading says that it can be multiplied.
I know a jet doesnt have transmissions and gear ratios and all that cool stuff, but isnt using different arms to achieve the best mechanical advantage increasing the torque at the flight control?
Sorry about the car analogy, but I am a knuckle dragger and that is all I know.
