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 98.90283523694194 > 94.2632130817522.
IsChangePoint: Marked as a change because one of 5/20/2022 7:31:10 PM, 5/31/2022 10:14:36 PM, 6/2/2022 10:01:42 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 10:01:42 AM.
IsRegressionStdDev: Marked as regression because -29.497348515040482 (T) = (0 -99.47881066416) / Math.Sqrt((0.45690008110611646 / (40)) + (0.49009148609268294 / (5))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (40) + (5) - 2, .025) and -0.1087628805532235 = (89.72054567205973 - 99.47881066416) / 89.72054567205973 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.
