  1. The first half of the table pertains to the unwanted sources of uncertainties, while the second half contains the controlled alteration of the test conditions. Based on the normality test results for the samples, either Student’s or Wilcoxon T-test was used for the significance test. Significant results are highlighted by green background. For the re-fixation parameter, due to lack of sufficient sample size, only the average % Diff is reported. The average repetition error (CV%) for all load cases was 1.53% (95% confidence interval [0.32, 2.75])
