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 < 0.00893453218513533.
IsChangePoint: Marked as a change because one of 9/30/2023 3:20:18 PM, 10/1/2023 7:44:15 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 2.7726703426109585 (T) = (0 -0.011678072111284066) / Math.Sqrt((0.24867998077618497 / (173)) + (0.004636830520035925 / (34))) is greater than 1.9716034992643237 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (173) + (34) - 2, .975) and 0.9040218460122951 = (0.12167427300987735 - 0.011678072111284066) / 0.12167427300987735 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
