In this case, with a $35 torque wrench I believe the error factor originally when it's new is similar if not the same. It is factory calibrated after all. The difference is that with usage it probably looses that calibration at a faster rate. But like I said I'm only going to use it once or twice a year. I'm 61, if I use it twice a year until I'm 75 that is only 28 uses. A mechanic could use one easily that much in a month. Plus I could buy another one in that time and still spend less and it's still better than using a standard wrench with your "that seems tight enough" idea.
