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 3.4071044833419735 < 4.220170090690543.
IsChangePoint: Marked as a change because one of 2/15/2022 10:33:05 PM, 2/17/2022 2:02:19 AM falls between 2/8/2022 9:17:51 AM and 2/17/2022 2:02:19 AM.
IsImprovementStdDev: Marked as improvement because 77.11072084059433 (T) = (0 -3.4298412032363323) / Math.Sqrt((0.010211180098645613 / (299)) + (0.00038961966145959647 / (3))) is greater than 1.9679030112610798 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (3) - 2, .975) and 0.22356346872469718 = (4.417413484657648 - 3.4298412032363323) / 4.417413484657648 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
