Why scorekeeping deserves a little preparation
Most disagreements during casual play are not really about arithmetic. They happen because the group did not agree on whether the highest or lowest score wins, when a match ends, whether a lead must be clear by two points, or who is responsible for recording each change. A thirty-second rules check before play prevents much longer interruptions later.
Good records are also useful after the winner is announced. A readable history helps players correct an accidental entry, resume an unfinished match, repeat a favorite setup, and understand which results belong in long-term statistics. The goal is not to make a casual game formal. It is to remove avoidable friction so everyone can focus on playing.
