I can't disagree with anything that you say here IF someone has an accurate torque wrench for the extremely low range that is required. But I'm giving my advice to those in general who will use a torque wrench that could get them in trouble with inaccurate torque applied. Heck someone just mentioned that they didn't even have miniature needlenose pliers to pull out the oil seals!
I snugged mine up by hand gently 10,000 miles ago and I'll bet it never gives me a problem. Yes, it does require a bit of experience wrenching around cars.
And if my falling out of the sky was dependent upon the precision of 6 ft-lbs, I'd be out buying that $300 low range electronic torque wrench! All of life cannot be as precise as is needed there.
