Description of detection logic

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 201.90997037390574 < 243.988516368302.
IsChangePoint: Marked as a change because one of 3/21/2022 1:28:14 PM, 3/22/2022 2:14:22 AM falls between 3/13/2022 11:50:20 AM and 3/22/2022 2:14:22 AM.
IsImprovementStdDev: Marked as improvement because 157.6093409029642 (T) = (0 -202.25737674151435) / Math.Sqrt((0.22020911441481003 / (299)) + (0.2413823685100218 / (2))) is greater than 1.9679296690655894 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (2) - 2, .975) and 0.21355307584463437 = (257.17867351154854 - 202.25737674151435) / 257.17867351154854 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
