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 2.5768095833333335 > 2.492523640625.
IsChangePoint: Marked as a change because one of 6/15/2022 10:21:53 PM, 8/2/2022 9:59:24 PM, 8/5/2022 10:47:59 PM falls between 7/28/2022 9:13:34 AM and 8/5/2022 10:47:59 PM.
IsRegressionStdDev: Marked as regression because -72.9682421997663 (T) = (0 -2596284.820826104) / Math.Sqrt((34960563.07275271 / (55)) + (174244970.51468956 / (19))) is less than -1.9934635666612892 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (55) + (19) - 2, .025) and -0.09650449265670057 = (2367783.112803864 - 2596284.820826104) / 2367783.112803864 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.
