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 1.7406803453894941 > 1.6819367311070637.
IsChangePoint: Marked as a change because one of 4/25/2022 11:05:49 AM, 4/25/2022 9:58:40 PM falls between 4/17/2022 3:50:42 AM and 4/25/2022 9:58:40 PM.
IsRegressionStdDev: Marked as regression because -9.435750566312656 (T) = (0 -1749.478683294569) / Math.Sqrt((1470.4349002962524 / (57)) + (154.82149978375764 / (2))) is less than -2.0024654592901125 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (57) + (2) - 2, .025) and -0.057969184031524096 = (1653.6196986645314 - 1749.478683294569) / 1653.6196986645314 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.
