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 2.9226499471522622 > 2.6453060919030658.
IsChangePoint: Marked as a change because one of 4/7/2022 3:14:09 PM, 5/12/2022 6:11:54 PM, 5/30/2022 10:25:35 AM, 5/31/2022 8:51:40 AM falls between 5/22/2022 6:37:49 PM and 5/31/2022 8:51:40 AM.
IsRegressionStdDev: Marked as regression because -26.89453573659349 (T) = (0 -2907.5634862339707) / Math.Sqrt((3942.730120111292 / (61)) + (546.5522642289455 / (4))) is less than -1.9983405425199077 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (61) + (4) - 2, .025) and -0.15105042033207072 = (2526.0087958572285 - 2907.5634862339707) / 2526.0087958572285 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.
