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 13.265757181777808 < 19.096106423052873.
IsChangePoint: Marked as a change because one of 11/17/2021 12:07:43 AM, 11/22/2021 8:11:44 PM, 11/30/2021 1:15:51 AM falls between 11/20/2021 4:23:58 PM and 11/30/2021 1:15:51 AM.
IsImprovementStdDev: Marked as improvement because 4.820382013299881 (T) = (0 -13.923131106071308) / Math.Sqrt((2.8839117978323423 / (299)) + (0.42392479607547334 / (30))) is greater than 1.9672451058622664 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (30) - 2, .975) and 0.05067890501337603 = (14.666408636234388 - 13.923131106071308) / 14.666408636234388 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
