Yes I get it. A dual, tri, and quad informs us of the number of teams involved. By your definition you will be dualing, triing, and quading the other teams instead of dueling each team. For the record spell check wouldnt allow me to use those three descriptions, I had to override spell check. Maybe spell check is onto something?
If you guys want to cry about the word I use then by all means go ahead.
Have a nice day.
