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 263.05155889194515 < 0.9551548529485301.
IsChangePoint: Marked as a change because one of 7/10/2022 3:20:59 AM, 7/12/2022 6:44:07 AM falls between 7/3/2022 4:26:07 AM and 7/12/2022 6:44:07 AM.
IsImprovementStdDev: Marked as improvement because 782.9147100497612 (T) = (0 -262.32589943251907) / Math.Sqrt((67.01790104799946 / (299)) + (7.961570626129659 / (12))) is greater than 1.9676708853560316 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (12) - 2, .975) and 0.7376561121422056 = (999.9314318872748 - 262.32589943251907) / 999.9314318872748 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
