I think, before you can say what a good result from a spanking should be, you need to ask why the spanking was administered. Was it a playful spanking, or was it for punishment? Or was it maybe a punishment that led to a reward for taking said punishment well? A playful spanking should be expressed as such, and would hopefully lead to a happy acceptance and further fun activities. A punishment spanking should lead to a desire on the part of the spanked to never draw such a punishment again Not that it should be harsh or unduly painful. A punishment spanking, even a light one, should focus more on the mental and emotional aspects of the punishment, the disappointment that led to said punishment. As in all other things, a punishment spanking should never be delivered out of anger. A punishment leading to a reward should have the same effect as a punishment spanking, while at the same time making it clear that being punished does not in any way make the spanker think or feel less of the spankee.
