As seen in Figure 11, virtually no difference is observed between the cumulative distributions until the 90th percentile. Small discrepancies occur at the 55th and 60th percentile, but in both cases, the differences in the plots are less than 0.3 με. At the 85th percentile, both the transverse and longitudinal strain gauges had absolute differences of approximately 6 με. After this point, the longitudinal gauges tended to show slightly more variability. These values might be the result of outliers which could be due to data processing errors or voltage spikes. The outliers did not come
from the same gauge; therefore, it is unlikely that a single gauge is at fault for the larger differences.
