    From Champion Radio ( <A HREF="";></A> ) - thanks!

    That's based on 70 degrees F. Guys will loosen as the temperature 
increases and the guys expand and they will tighten as the temp decreases and 
the guys contract so the measured values will change also.

    If you were that close with "eyeballing" - congratulations! You're a 
helluva lot closer than any I've ever seen. 
    If you're within 5%, I could live with that. One of the important things 
is that the guys are all equalized and you're ensuring that that's the case.
