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 227.12627510779262 < 510.3927361891066.
IsChangePoint: Marked as a change because one of 6/15/2022 1:30:25 PM, 6/23/2022 8:35:19 AM falls between 6/14/2022 4:54:48 PM and 6/23/2022 8:35:19 AM.
IsImprovementStdDev: Marked as improvement because 56.462693040061936 (T) = (0 -247.55141205704768) / Math.Sqrt((1340.9705704545527 / (152)) + (409.17942640786026 / (30))) is greater than 1.9732308230712676 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (152) + (30) - 2, .975) and 0.5194559104194674 = (515.1481777106769 - 247.55141205704768) / 515.1481777106769 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
