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 65.16999004795446 < 1.3384590673765477.
IsChangePoint: Marked as a change because one of 10/26/2022 7:25:48 AM, 10/27/2022 12:34:03 AM falls between 10/18/2022 9:26:37 AM and 10/27/2022 12:34:03 AM.
IsImprovementStdDev: Marked as improvement because 129.4747505966955 (T) = (0 -57.423710470988475) / Math.Sqrt((13793.098666869659 / (299)) + (120.00969456904055 / (2))) is greater than 1.9679296690655894 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (2) - 2, .975) and 0.958726587748909 = (1391.3002908905457 - 57.423710470988475) / 1391.3002908905457 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
