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 3.440952895522388 > 3.275119675788426.
IsChangePoint: Marked as a change because one of 5/27/2022 6:33:44 PM, 6/2/2022 10:01:42 AM falls between 5/24/2022 3:42:52 PM and 6/2/2022 10:01:42 AM.
IsRegressionStdDev: Marked as regression because -5.716394021394091 (T) = (0 -3606195.9445370575) / Math.Sqrt((51026108488.539795 / (20)) + (62699593488.91942 / (20))) is less than -2.0243941639098457 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (20) + (20) - 2, .025) and -0.1357606713716952 = (3175137.1881734002 - 3606195.9445370575) / 3175137.1881734002 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.
