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 22.324942764475818 < 36.18285739186411.
IsChangePoint: Marked as a change because one of 4/10/2023 1:33:42 PM, 5/1/2023 10:17:01 AM, 5/9/2023 7:24:34 AM falls between 4/30/2023 6:17:41 PM and 5/9/2023 7:24:34 AM.
IsImprovementStdDev: Marked as improvement because 43.51831277846727 (T) = (0 -22.961537368187162) / Math.Sqrt((8.17435580009631 / (299)) + (0.6230409718208308 / (35))) is greater than 1.9671350567190904 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (35) - 2, .975) and 0.2870755052202067 = (32.20753044160655 - 22.961537368187162) / 32.20753044160655 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
