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 457.5180578 > 354.75521674923084.
IsChangePoint: Marked as a change because one of 12/28/2022 7:19:51 AM, 1/5/2023 2:25:12 AM falls between 12/27/2022 1:08:06 PM and 1/5/2023 2:25:12 AM.
IsRegressionStdDev: Marked as regression because -3376.22042670025 (T) = (0 -457705277.2700001) / Math.Sqrt((1139388660.673154 / (9)) + (22674952947.630074 / (20))) is less than -2.051830516474954 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (9) + (20) - 2, .025) and -0.35477942570767834 = (337844868.7548636 - 457705277.2700001) / 337844868.7548636 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.
