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 15.634575002886393 < 18.101754692663427.
IsChangePoint: Marked as a change because one of 9/18/2023 8:11:22 PM, 9/24/2023 11:15:45 PM, 10/5/2023 8:44:34 AM, 10/11/2023 8:44:35 PM falls between 10/3/2023 8:20:31 AM and 10/11/2023 8:44:35 PM.
IsImprovementStdDev: Marked as improvement because 8.14645194576725 (T) = (0 -16.386726453513003) / Math.Sqrt((3.488863903586673 / (199)) + (1.09359422903031 / (25))) is greater than 1.9707073953201992 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (199) + (25) - 2, .975) and 0.10957645454715535 = (18.40329418196053 - 16.386726453513003) / 18.40329418196053 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
