Takeaway
- M1 shows how fast uncertainties fell; M2–M4 how well those uncertainties covered the moves between editions; M5 and M6 the history of each constant and the transitions to exact values.
- Every number carries its sample size and a 95% interval; definitions, formulas, denominators and caveats are on each page.
