What YOU have been saying , Thats what we have been telling YOU all along. How many times have we told you that TILTING the extension will affect the applied torque by introducing a leverage factor into the equation. There are many ways to improperly use a torque wrench or any other tool and that holding illustration is just another example of a mechanically induced error. What they are saying is DON'T DO THAT that shows how NOT to use a torque wrench!
What exactly do you think you have found here? This started when you tried to say that an extension would be in error because of twisting and you could not prove that so you have gone off in several other directions since claiming everything from inertia to a full moon would effect the reading.
How much time have you spent searching the net for info to back up your point and you say you are not obsessed? If you would have the common courtesy to answer just ONE question I would like for you to explain why it is so hard to find credible info to back up what you STARTED OUT saying but the opposite info is easy to find, why is that? If you can't answer that then how about which one of those torque wrenches connected together would read less, which one? Why?
