```
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 72.31876932012298 > 70.45546285171473.
IsChangePoint: Marked as a change because one of 9/17/2023 8:50:51 AM, 9/25/2023 10:28:34 PM falls between 9/17/2023 8:50:51 AM and 9/25/2023 10:28:34 PM.
IsRegressionStdDev: Marked as regression because -3.443064917913446 (T) = (0 -72.7002111242899) / Math.Sqrt((16.156374631906683 / (12)) + (2.204552512454975 / (39))) is less than -2.0095752371279447 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (12) + (39) - 2, .025) and -0.059428278277145856 = (68.62211686714252 - 72.7002111242899) / 68.62211686714252 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
