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.
IsRegressionWindowed: Marked as regression because 1.1600730084672544 > 1.1182728509630493.
IsChangePoint: Marked as a change because one of 10/6/2022 12:41:43 AM, 10/17/2022 12:47:34 PM, 10/25/2022 2:56:59 AM falls between 10/16/2022 1:15:28 PM and 10/25/2022 2:56:59 AM.
IsRegressionStdDev: Marked as regression because -18.128054119702597 (T) = (0 -1158.1561265420733) / Math.Sqrt((205.36996658651944 / (16)) + (324.0841258983043 / (29))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (16) + (29) - 2, .025) and -0.08307019798741111 = (1069.32692700269 - 1158.1561265420733) / 1069.32692700269 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.
