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 460.45242909663864 < 488.93993809523806.
IsChangePoint: Marked as a change because one of 5/9/2022 6:32:22 AM, 8/2/2022 9:32:02 PM, 8/11/2022 10:02:44 AM falls between 8/2/2022 9:32:02 PM and 8/11/2022 10:02:44 AM.
IsImprovementStdDev: Marked as improvement because 426.82410753841543 (T) = (0 -460173.8796191555) / Math.Sqrt((1761612.9510928676 / (299)) + (210802.16832529882 / (19))) is greater than 1.9674995188240387 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (19) - 2, .975) and 0.10784935356627681 = (515802.88761617936 - 460173.8796191555) / 515802.88761617936 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
