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 62.71456346153847 > 43.72192386072397.
IsChangePoint: Marked as a change because one of 12/17/2022 9:10:43 AM, 1/18/2023 3:58:17 AM, 2/9/2023 4:27:10 AM, 2/14/2023 7:27:15 AM falls between 2/5/2023 7:19:43 PM and 2/14/2023 7:27:15 AM.
IsRegressionStdDev: Marked as regression because -30.829590911328257 (T) = (0 -62189.74143876065) / Math.Sqrt((13526987.511518937 / (32)) + (55299.32066887307 / (23))) is less than -2.005745995316835 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (32) + (23) - 2, .025) and -0.47759790630807714 = (42088.4065775024 - 62189.74143876065) / 42088.4065775024 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.
