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 258.26950842505784 > 224.38375059660774.
IsChangePoint: Marked as a change because one of 2/3/2022 7:42:52 AM, 2/26/2022 3:32:05 AM, 3/17/2022 6:54:53 PM, 4/19/2022 10:22:09 AM, 4/21/2022 7:46:01 AM falls between 4/12/2022 3:59:36 PM and 4/21/2022 7:46:01 AM.
IsRegressionStdDev: Marked as regression because -55.546319547567485 (T) = (0 -257.33782679618514) / Math.Sqrt((2.2167638112656336 / (36)) + (2.627565747056526 / (5))) is less than -2.0226909200346674 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (36) + (5) - 2, .025) and -0.19816152805078524 = (214.77724060697568 - 257.33782679618514) / 214.77724060697568 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.
