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.

IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed: Marked as improvement because 4.256221917452512 < 7.310916391874175.
IsChangePoint: Marked as a change because one of 3/21/2023 2:53:21 PM, 3/30/2023 4:24:24 AM falls between 3/21/2023 2:53:21 PM and 3/30/2023 4:24:24 AM.
IsImprovementStdDev: Marked as improvement because 7.923211658180366 (T) = (0 -6.018644520740384) / Math.Sqrt((1.6603669886450352 / (299)) + (1.2343574205039127 / (30))) is greater than 1.9672451058622664 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (30) - 2, .975) and 0.22147540442245026 = (7.730834137970224 - 6.018644520740384) / 7.730834137970224 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
