Eternity I veteran; the list's numbers-checker

An Eternity I veteran and the list's earliest sceptic of prize-solvability estimates. In 2001 he asked how one would design a puzzle carrying a huge prize with roughly a one percent chance of being solved in ten years. For two decades he checked the list's numbers, from exact-cover conversions to the nodes-per-watt hardware ledger.
