Is there more than one way to create the draw for a USTA sanctioned singles tournament? It is my understanding that "seeds" are the highest ranked players in the tournament. For a round of 32, the #1 and #2 seeds go in slots 1 and 32. #3 and #4 seeds go in slots 16 and 17. You then fill the next placements, according to rankings, in slots 8, 25, 9 and 24, respectively. You then fill the rest with the remaining people -- ranked highest to lowest (most of them are unranked). Is this correct?
