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 55.65748180357939 < 74.66273087650865.
IsChangePoint: Marked as a change because one of 11/22/2021 3:34:51 PM, 1/31/2022 1:37:35 PM, 2/8/2022 11:58:21 PM falls between 1/31/2022 9:06:05 AM and 2/8/2022 11:58:21 PM.
IsImprovementStdDev: Marked as improvement because 50.364796093215226 (T) = (0 -54.382813615363766) / Math.Sqrt((28.805637391992693 / (236)) + (3.209558926991595 / (32))) is greater than 1.9689223241413707 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (236) + (32) - 2, .975) and 0.30396393923060355 = (78.13217831738365 - 54.382813615363766) / 78.13217831738365 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
