Just because you have more causes of error doesn't mean you have lesser accurate measures. If fact, errors may compensate each other. It all depends on the bias (accuracy) and variation (precision) involved in the measurements you are considering. > -- > Wulfraed Dennis Lee Bieber AF6VN > wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/ > > -- > http://mail.python.org/mailman/listinfo/python-list
