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 47.8391887449187 > 28.413704548766663.
IsChangePoint: Marked as a change because one of 1/5/2023 4:05:11 PM, 3/8/2023 4:26:04 PM, 3/14/2023 1:07:29 AM falls between 3/5/2023 5:11:19 AM and 3/14/2023 1:07:29 AM.
IsRegressionStdDev: Marked as regression because -417.47007129757554 (T) = (0 -47946.1456281008) / Math.Sqrt((8893.150806004587 / (25)) + (34361.95092268937 / (16))) is less than -2.0226909200346674 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (25) + (16) - 2, .025) and -0.7719328277930384 = (27058.66998796915 - 47946.1456281008) / 27058.66998796915 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.
