-name: Performance - Score Director
+# - Runs entirely on a single machine.
+# - The baseline is established first, then the branch under test is measured.
+# - Each benchmark gives a 99.9 % confidence interval.
+# - The confidence intervals are compared to determine if the branch under test is a regression or an improvement.
+# - The error threshold is expected to be below +/- 2.5 %.
+#   We have yet to see an error of over +/- 4 %.
+#   With the error so high, the impact is that small regressions are not considered statistically significant.
