IV — Observations and Data

A — Calibration Measurement Table

Known reference distance: 50.000 m.

All seven calibration observations remain visible in the raw record. Only the single highest and single lowest values are excluded from the calibration mean, leaving five retained calibration counts for the pace-factor computation.

C — Computed Data Summary

V — Computations and Assumptions

A — Trimmed Mean Calibration Count

$$\sum N_i=64+63+64+65+63+64+62=445\text{ paces}$$ $$\overline{N}_{\mathrm{trim}}=\frac{445-65-62}{7-2}=\frac{318}{5}=63.6\text{ paces}$$

B — Pace Factor

$$PF=\frac{50.000}{63.6}=0.7861635\text{ m/pace}\approx\boxed{0.7862\text{ m/pace}}$$

C — Unknown-Line Check

$$\overline{N}_{\mathrm{unknown}}=\frac{92+93+92+92+93}{5}=92.4\text{ paces}$$

Using the unrounded pace factor in the calculation,

$$D_{\mathrm{paced}}=92.4(0.7861635)=72.6415\text{ m}\approx72.642\text{ m}$$ $$E=72.6415-72.500=+0.1415\text{ m}\approx+0.142\text{ m}$$ $$\%E=\frac{|72.6415-72.500|}{72.500}(100)=0.1952\%\approx0.195\%$$

Assumptions and conventions:

• One individual step is counted as one pace.
• The 50.000 m calibration baseline is the independently measured horizontal reference distance.
• Exactly one highest and one lowest calibration count are excluded from the mean while remaining visible in the raw record.
• The five retained calibration observations are the only counts used to determine the pace factor.
• The unknown-line check is tabulated separately and uses five complete pacing trials.
• The same adopted pace factor is used for the independent unknown-line pacing check.
• Unrounded values are retained through intermediate computations; reported values are rounded only at the final presentation stage.
• The independently taped unknown-line distance is used only as the accuracy check and not to determine the pace factor.

VI — Remarks and Conclusions

A — Remarks

• Natural gait was established before the first calibration trial.
• All seven raw calibration counts were retained in the field record, including the excluded highest and lowest observations.
• Forward and reverse walking directions were alternated where practical to reduce directional bias.
• Five separate unknown-line trials were completed and tabulated independently from the calibration table.
• The calibration and unknown-line surfaces were dry and unobstructed during the representative activity.
• Likely error sources include gait inconsistency, judging the exact station crossing, distraction, and surface changes.
• Pacing remains an approximate reconnaissance method and does not replace direct or instrument-based measurement where higher accuracy is required.

B — Conclusion

The adopted individual pace factor is 0.7862 m/pace using the course convention that one step equals one pace. It was derived from seven raw calibration trials after excluding only the single highest and single lowest observations from the mean. Applying the factor to the five-trial unknown-line average produced a paced distance of 72.642 m, compared with the independently taped value of 72.500 m, for an absolute percentage error of 0.195%. The result demonstrates a consistent single-baseline pace calibration suitable for reconnaissance-level distance estimation.
