, guess my question is, if you balance the plane where the manufacture says too, what shoukd i look for that might indicate the manufacture's cg is off?
You could find out what a fullscale manufacturer would use for a CG.
As for interpreting how much lead it's taking to balance, that won't tell you a thing about whether the mfg was off on his CG. Because it just as easily tells you he blew his wood sizes and choices or the construction details.
