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 100.2543846328221 > 94.13587749587735.
IsChangePoint: Marked as a change because one of 12/1/2022 8:17:56 AM, 12/14/2022 5:20:21 PM, 12/20/2022 4:30:45 AM falls between 12/11/2022 2:11:02 PM and 12/20/2022 4:30:45 AM.
IsRegressionStdDev: Marked as regression because -117.49386817088953 (T) = (0 -100.04270290489245) / Math.Sqrt((0.13963487734764332 / (33)) + (0.07869711829999565 / (24))) is less than -2.0040447832881556 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (33) + (24) - 2, .025) and -0.11331272407218222 = (89.86037861757711 - 100.04270290489245) / 89.86037861757711 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.
