"One guy has a set that averages 6.52, and the other guy has a 6.48. Can you tell me who has the better set? I wouldn't have a clue. Maybe the guy with the 6.48 really has the better set, and the other guy's is overgraded. Nobody knows for sure, as the numbers are meaningless."
Actually you are right as a matter of statistics -- an average cannot have any more significant figures than the underlying data. An 8 really just means somewhere between 8.0 and 8.5; and 8.5 just means somewhere between 8.5 and 9.0. So strictly speaking an average out to the hundredths place is a false precision.
