Description of detection logic

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 21.965768333333333 > 20.191599749999998.
IsChangePoint: Marked as a change because one of 4/6/2022 12:51:22 AM, 4/16/2022 5:36:25 PM, 5/9/2022 5:23:46 PM, 5/10/2022 11:18:06 AM, 5/17/2022 3:30:02 AM falls between 5/8/2022 12:35:08 PM and 5/17/2022 3:30:02 AM.
IsRegressionStdDev: Marked as regression because -22.207181782118155 (T) = (0 -21986511.75595238) / Math.Sqrt((312379919749.41565 / (28)) + (6396200809.007886 / (4))) is less than -2.0422724562973107 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (28) + (4) - 2, .025) and -0.12876203857851154 = (19478429.469191525 - 21986511.75595238) / 19478429.469191525 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.
