Men's 110mH metric
Coach notes
  • The tape canon manual: "Display to 0.01 m. Do not round metric marks down to tenths."
  • The aligned-headers and final-ordered charts: "Rounded down to the nearest tenth."
  • Both variants are computed independently from the same source spacings. The tenths mark is never longer than the 0.01 m mark and never more than 0.08 m shorter.
  • The final-ordered chart labels the colors 7.9, 8.2, 8.5, 8.8 and 9.1 m. Those are rounded labels, not spacings. Adding 7.9 m nine times gives 71.1 m at H10; the true Red H10 mark is 71.46 m, a drift of 0.36 m.

  • Ambiguity Which men's metric display governs, 0.01 m or rounded-down tenths. The sources conflict; the founder has not ruled. Both are shipped and labelled.

  • The Tape System -- H1 is zero. One color down the track. Colors are practice spacings; black is race truth.
  • The Tape Ladder Is the ABC Ladder -- Red, Blue, Green and Yellow sit 4, 3, 2 and 1 feet under race spacing: the A, B, C reps and the working-set home.
