In normal ACBL bridge club tournament, to even things out the first round table 1, an A level team plays an A level team, table 2 is a B level tesm plays a B level team and the 3rd table a C level team plays a C level team and an attempt is made to continue this sequence. The purpose is to even the field so each team level plays an equal level of a ABC level teams. This avoids the semi random setup I see presently where C level teams sometimes play a disproportionate number of A level teams and A level teams get to beat up on a disproportionate number of C level teams. I have seen a couple of events were a B level team played 4 A level teams and got beat by an A level team by 2 points in raw score that had play 3 C level teams, a really good day for the B team but not really a level playing field. Leveling the playing field at the beginning of play would at least guarantee playing against the same number of ABC teams or close to it.
