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 861.141181956194 < 0.9771273574632926.
IsChangePoint: Marked as a change because one of 5/11/2022 3:41:15 PM, 6/2/2022 5:58:32 PM, 6/9/2022 4:58:43 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 4:58:43 AM.
IsImprovementStdDev: Marked as improvement because 14.465960409546891 (T) = (0 -861.2458717022034) / Math.Sqrt((6846.865774711748 / (148)) + (0.0397806371168148 / (26))) is greater than 1.9738521694944169 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (148) + (26) - 2, .975) and 0.10253240117617939 = (959.6400726119944 - 861.2458717022034) / 959.6400726119944 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
