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 3.7350780000000006 > 3.5690339922669025.
IsChangePoint: Marked as a change because one of 3/17/2022 6:54:53 PM, 5/20/2022 10:46:48 AM, 5/24/2022 7:58:36 AM falls between 5/15/2022 6:57:22 PM and 5/24/2022 7:58:36 AM.
IsRegressionStdDev: Marked as regression because -28.175111592613163 (T) = (0 -3747952.2852820847) / Math.Sqrt((1010164643.7378092 / (39)) + (1820187968.008297 / (17))) is less than -2.0048792881871513 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (39) + (17) - 2, .025) and -0.09491416031449038 = (3423055.8167277393 - 3747952.2852820847) / 3423055.8167277393 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.
