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 4:22:12 AM, 5/30/2023 4:48:39 PM, 6/7/2023 7:43:49 PM falls between 5/29/2023 11:58:32 PM and 6/7/2023 7:43:49 PM.
IsImprovementStdDev: Marked as improvement because 4.707745900157109 (T) = (0 -5376.11704973244) / Math.Sqrt((302115.38119073515 / (299)) + (64147.60277040313 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.06146043717707229 = (5728.1730708956175 - 5376.11704973244) / 5728.1730708956175 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
