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 0.9883992902337841 < 2.944136608110269.
IsChangePoint: Marked as a change because one of 10/2/2023 2:58:00 AM, 10/9/2023 8:09:24 PM falls between 10/1/2023 7:44:15 AM and 10/9/2023 8:09:24 PM.
IsImprovementStdDev: Marked as improvement because 5.705641359925347 (T) = (0 -1.3384907841215685) / Math.Sqrt((0.9326771916654198 / (176)) + (0.7442457005195041 / (30))) is greater than 1.9716608894935834 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (176) + (30) - 2, .975) and 0.42517179430665486 = (2.3285057533095657 - 1.3384907841215685) / 2.3285057533095657 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
