I guess its almost impossible to determine if a frame is "as good as new" without sophisticated equipment, but its not that hard to deem it cracked with almost no equipment.
And thats pretty much what the lbs'es are trying to determine. is it a scratch or a crack? thats it. they are not trying to quantify the level of crackedness. and they dont need to. No reason to.
I feel many people are creating a storm it a drinking glass just because it made out of carbon fiber.
And its kinda funny since this is the best material in the entire universe, proven by science too. so its should not be able to break at all. right.
