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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 5/19/2023 10:30:38 AM, 7/25/2023 7:04:35 PM, 7/27/2023 9:58:25 PM falls between 7/18/2023 9:38:16 PM and 7/27/2023 9:58:25 PM.
IsImprovementStdDev: Marked as improvement because 53.43835937469551 (T) = (0 -42.46568426336467) / Math.Sqrt((14.719911204864708 / (299)) + (0.0071138340410771845 / (6))) is greater than 1.967824097752068 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (6) - 2, .975) and 0.2203050226597336 = (54.46448354486736 - 42.46568426336467) / 54.46448354486736 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
