Before the group arrivesCheck your supplies, clear a little inventory space, and decide what you want to practice. Share the plan before the first pull, when everyone still has time to ask questions.
During a difficult encounterKeep callouts short. Focus on the next safe position and the next shared decision rather than replaying the last mistake. Leave room for your teammates to recover.
After the sessionSave one useful observation and one moment worth remembering. Progress is easier to see when you keep notes across several evenings, not just the final attempt.
