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 1.0547845964714895 < 472.82158997252753.
IsChangePoint: Marked as a change because one of 2/14/2022 7:55:17 PM, 2/22/2022 12:12:47 AM falls between 2/13/2022 12:11:49 PM and 2/22/2022 12:12:47 AM.
IsImprovementStdDev: Marked as improvement because 833.7820731978377 (T) = (0 -1056.5709122699932) / Math.Sqrt((7837513.761085998 / (22)) + (342.59140211227725 / (45))) is greater than 1.9971379083914016 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (22) + (45) - 2, .975) and 0.9978814311619143 = (498719.179323281 - 1056.5709122699932) / 498719.179323281 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
