15 years of truck mechanic, 24 years of automotive machinist, and not ready to quit for a while yet.why do you claim 2 grams? we claim less than 1 and are usually not satisfied till it's below a half.
 
2 or less is usually good for high rpms. Most shops are 4 to 6 grams out the door. 2 or less can take 2 to three days to get. We have found the less grams-inch you can get the easier it is on the main bearings and caps.
 
some come in real easy. others are a real pain. when you get them real close, and do the whole rotating assembly. they are amazingly smooth. the throttle is like a volume knob. no sensation just more noise. most people don't even realize the effect.
 

I agree if it enteranlly balanced the balancer hub. Flywheel pressure plate need to be spun and at minimum set to neutral if not used to externally balance
