I humbly accept my "Wrong Answer" status and thank you, Kev, for the lesson. I chose only "Top 1000..." as I had thought that "TOP n PERCENT" and "TABLESAMPLE..." were both imprecise in determining the number of rows returned. Your answer (and the MS doc) show "TOP n Percent" really works.

This was a good QOTD for me in that it taught me about that specific difference.
