A two beam setup would allow differentiation between entering and exiting of single clients. Then the question comes down to how often do 2+ people cross the beams at once, and does that have enough of an effect on the aggregate statistics, if it was taken into account (e.g. count each crossing as 1.1 people, if 10% of beam crossings are 2 people)?
