I'd say to keep your eye out for anyone using air... not to imply that people not using air tools are any brighter. I found that my air wrench tightens to 78 ft-lbs consistently on stage one, but any idiot can and may decide to crank it up just to make sure they're on there good'n tight. I found my lugs had been tightened to 220 ft-lbs the first time I tried to take the wheels off. I had to go buy a breaker bar just to get them off because a couldn't physically exert enough force on my ratchet.. long story short, that was probably due to someone with an air wrench... or maybe a really heavy guy leaning into it? :P siigh...
