if you have both readings very low and near 0, would that be considered as a healthy engine?

A healthy engine would stay within 0-5 negative or positive at all times. There would be observable, but normal correction of the fuel trims but ideally I look at a healthy engine as within 0-5 either way and no higher than 10.
