If everyone is within two cards of each other (say a five, two eights, and a thirteen), the team just adds them all up and takes the average (in that case 6.6) and moves on to the next item. Remember, we’re talking estimates, not ironbound schedules. And estimates on small pieces of the project. If people are more than three cards apart, then the high and the low cards talk about why they think what they do. Then everyone does another round of Planning Poker.
