I think you guys might be talking past each other, here. What Lenny is saying (and I agree with him) is that the NUMBER your gauge gives you is pretty meaningless. Only two things matter: 1) the number displayed on your gauge is the number at which the car reliably hooks, 60-foots well, and is safe at the other end; and 2) the gauge which produces the number does not vary at all in its measurement and display of said number. It is completely
reliable.
If my gauge tells me that my tire pressure is 27 psi, and 9 other gauges read within a quarter of a pound of 22 pounds, what do I care what my gauge reads, as long as my 27 pounds always corresponds to the 22 pounds seen on all the other gauges? If, every time I check my tire pressure, I see 27 pounds, I know I'm right where I need to be.
The only legitimate concern is that I might worry because I don't know the ACTUAL tire pressure, but the whole point of this discussion is that I really NEVER know the perfect pressure, because there is always variation in gauges. Kinda like the outdoor thermometers on bank signs...
