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.

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 636.3207727580372 < 694.6160062134161.
IsChangePoint: Marked as a change because one of 5/20/2023 3:57:43 PM, 5/31/2023 1:59:31 PM, 6/11/2023 6:04:57 PM, 6/14/2023 3:35:53 PM falls between 6/5/2023 10:09:45 PM and 6/14/2023 3:35:53 PM.
IsImprovementStdDev: Marked as improvement because 57.40931673992486 (T) = (0 -633937.4949863642) / Math.Sqrt((3463167032.7351623 / (299)) + (7236889.890346942 / (4))) is greater than 1.9678765312856872 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (4) - 2, .975) and 0.2489116223239004 = (844025.1691123148 - 633937.4949863642) / 844025.1691123148 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
