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 16.638866859915005 < 18.517111102374983.
IsChangePoint: Marked as a change because one of 7/2/2022 7:35:06 PM, 7/6/2022 3:55:24 AM, 9/13/2022 9:36:44 AM, 9/22/2022 12:33:20 AM falls between 9/13/2022 9:36:44 AM and 9/22/2022 12:33:20 AM.
IsImprovementStdDev: Marked as improvement because 9.242468378267178 (T) = (0 -17.790719788834796) / Math.Sqrt((3.6326850185848722 / (299)) + (0.9889228695156351 / (38))) is greater than 1.967070609662329 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (38) - 2, .975) and 0.09214913996304867 = (19.596522481799134 - 17.790719788834796) / 19.596522481799134 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
