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 203.55764166666665 > 162.35867374999998.
IsChangePoint: Marked as a change because one of 12/28/2022 5:13:50 PM, 1/3/2023 6:29:42 AM falls between 12/23/2022 9:40:21 PM and 1/3/2023 6:29:42 AM.
IsRegressionStdDev: Marked as regression because -46.06234216162504 (T) = (0 -207340425.7440476) / Math.Sqrt((13056736513586.77 / (29)) + (11162983392259.783 / (14))) is less than -2.019540970439573 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (29) + (14) - 2, .025) and -0.33003574762099974 = (155890866.92963856 - 207340425.7440476) / 155890866.92963856 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.
