Torque Concept versus Torque Measurement
(This is a general reply to the topic as it began.)
There are different reasons for using a torque wrench. It must be kept in mind, however, a torque wrench is only a tool, and will not replace thinking. What a threaded fastener (nut & bolt) needs is an adequate amount of tension, which is simply not-too-little and not-too-much. This can be achieved by a truing the thread either by hand or by a torque wrench. A torque wrench is then a measuring tool, much like a spoke tensiometer, a tape measure, a caliper, or even a tablespoon or measuring cup for a cook. You can make a great cake by grabbing hands full of flour and pouring out the salt, but most people would not want to purchase such a cake at their local grocery store. A torque wrench, used correctly, makes a good mechanic better. However, if basic knowledge is lacking, a torque wrench will not act as "magic wand" making every component safe and secure. There is also a difference between working on your own bike, and working professionally on other peoples bikes. Correct use of a torque wrench is one more way a shop can stand fully behind its work. A quick look at various bicycle forums will show that the creaking bicycle is often an issue, making lack of torque knowledge wide spread.
