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 9.069007626542835 < 9.332975615239386.
IsChangePoint: Marked as a change because one of 12/7/2021 12:20:12 AM, 12/17/2021 7:05:08 PM, 1/5/2022 4:19:16 PM falls between 12/6/2021 2:46:54 PM and 1/5/2022 4:19:16 PM.
IsImprovementStdDev: Marked as improvement because 26.899973806803885 (T) = (0 -9.28439956141843) / Math.Sqrt((0.08026924221146005 / (181)) + (0.032554400663522574 / (76))) is greater than 1.969310569849703 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (181) + (76) - 2, .975) and 0.07880670618809602 = (10.078666034355855 - 9.28439956141843) / 10.078666034355855 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
