Aggregation of marginal gains wins championships

Dave Brailsford's principle of the aggregation of marginal gains, seeking 1% improvements in everything related to cycling (lighter tires, wind-tunnel-tested suits, handwashing surgeons, optimized pillows), transformed British Cycling from a century of mediocrity into a team that won multiple Tours de France and roughly 60-70% of available Olympic gold medals, showing small improvements can unlock elite success.
