Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 34.156796477850406 < 37.508457086399254.
IsChangePoint: Marked as a change because one of 4/16/2022 8:46:33 PM, 6/7/2022 11:31:29 PM, 6/9/2022 4:58:43 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 4:58:43 AM.
IsImprovementStdDev: Marked as improvement because 24.851475593639737 (T) = (0 -34239.93381103113) / Math.Sqrt((5161837.465897629 / (299)) + (6105.6079675498 / (3))) is greater than 1.9679030112610798 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (3) - 2, .975) and 0.09159365670536812 = (37692.31034522375 - 34239.93381103113) / 37692.31034522375 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
