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.
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 36.31446901669052 < 39.04682108528613.
IsChangePoint: Marked as a change because one of 4/1/2023 1:31:30 PM, 4/3/2023 9:14:01 PM falls between 3/26/2023 7:47:31 AM and 4/3/2023 9:14:01 PM.
IsImprovementStdDev: Marked as improvement because 22.769479902453984 (T) = (0 -36.37588340362497) / Math.Sqrt((0.0426038324524733 / (299)) + (0.3803189176526388 / (9))) is greater than 1.9677467375895035 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (9) - 2, .975) and 0.11417503406788079 = (41.06441430598881 - 36.37588340362497) / 41.06441430598881 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
