One of the main objectives of the QOD is to teach/educate and that your QOD has certainly done.
I agree with this. My comment about how the query could be modified so it'll always remove 9 rows was more from the attitude of, "If someone is dealing with this issue here's one way to handle it," and less from, "the question was poor." I certainly didn't know about this behavior before and it's good to know it's out there.
