Practice the TL, TC, TR, ML, MC, MR, BL, BC, and BR coordinate set until every player can point to a called cell without translation. Keep the exercise outside a serious Campaign attempt until every role can finish without inventing vocabulary. Then add a timer and one deliberate interruption. Rehearse the full BOMBANANA recovery: hands off, identify the break, declare stability, restart at “Soundboard,” and collect current fields. Use “hands off” as a state-control command, not criticism. Neutral language makes it easier to stop a nearly completed action when the evidence changes.
Measure packet accuracy before raw speed. Count missing fields, ambiguous positions, premature actions, and failed confirmations; only shorten pauses after the packet is reliable. Rotate BOMBANANA roles so everyone experiences observation, manual search, relay translation, and physical execution. Replay the longest exchange once without a timer and once under pressure. Compare where vocabulary changes, because that is usually where reliability disappears. Shared understanding is more useful than one player memorizing a table.
