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 29.298916923076927 > 28.86969814615385.
IsChangePoint: Marked as a change because one of 4/20/2022 8:23:28 AM, 5/23/2022 3:43:39 PM, 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 -50.203827738710984 (T) = (0 -29295.707692307697) / Math.Sqrt((91015.60543795506 / (55)) + (20.598324260357977 / (2))) is less than -2.0040447832881556 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (55) + (2) - 2, .025) and -0.07518661710402194 = (27247.091087512486 - 29295.707692307697) / 27247.091087512486 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.
