Description of detection logic
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 8.73044477646509 < 14.090138692012358.
IsChangePoint: Marked as a change because one of 6/22/2023 7:55:14 AM, 7/6/2023 4:13:54 AM, 7/10/2023 4:47:56 PM falls between 7/1/2023 10:14:52 PM and 7/10/2023 4:47:56 PM.
IsImprovementStdDev: Marked as improvement because 86.77744391437771 (T) = (0 -8.712534675799771) / Math.Sqrt((1.0279965127478072 / (215)) + (0.020827087589515035 / (12))) is greater than 1.9705633902925863 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (215) + (12) - 2, .975) and 0.4456928502804185 = (15.717882549787346 - 8.712534675799771) / 15.717882549787346 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
