Source spacings: Red 7.94, Blue 8.24, Green 8.54, Yellow 8.84, Black 9.14 m.The manual shows each mark to 0.01 m. Two field charts show the same marks rounded down to the tenth.
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.
