The explanation in the video "clicked" for me and with this style of wrench I would agree that position matters.
In my mind I was thinking more of a split beam style wrench. But now I'm questioning as to whether the split beam would also have hand position matter?
I think the beam parts in the split beam are tangent to the rotating part and may not be hand sensitive.
Split beam it still matters (see ronkz650's post above). AFAIK the only torque wrenches that it would not matter are those where the torque sensing mechanism is directly in line with the square drive, and the only ones I know like that are dial-type like this:1721740201782.jpeg

These have a "weak area" behind the square drive that is designed to flex a little to give the torque reading.

There may be others where hand position does not matter.

Just to answer the question whether hand position matters to myself, I took the liberty to do my own tests on a few different torque wrenches. All were tested at 30ft/lb
Snap on TQFR100C split beam= Matters a lot. Choke up on the handle and it applies 37ft/lb, put an extension on it applies 25ft/lb
Snap on Atech2FR100 Techangle=Matters, but only a couple ft/lb either way.
Sears Digitork clicker from 1981= Doesn’t matter
CDI 3/8 clicker= Matters, about 4ft/lb each way
Precision Instruments dial type= Doesn’t matter
So I guess the answer is it may/may not matter, but better off not taking the chance.
excellent work, sir!

I don't own a torque wrench. I've been using digital torque adapters (on the occasion when I use a torque spec) and one virtue of those is that it allows you to use a breaker bar and grab however you like.

I'm thinking I'll grab a split beam I can leave pre-set for common things like lug nuts which is one of the few things I have occasion to use a torque wrench on and it would be convenient vs breaking out the little digital box.

Those are the kind we used when I was doing C130 and B1B maintenance.
