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 7.933700139342826 < 8.238103691322873.
IsChangePoint: Marked as a change because one of 4/16/2022 5:36:25 PM, 5/30/2022 5:18:40 PM, 6/7/2022 9:00:42 AM falls between 5/29/2022 5:15:01 PM and 6/7/2022 9:00:42 AM.
IsImprovementStdDev: Marked as improvement because 26.319073945319087 (T) = (0 -8035.854007593581) / Math.Sqrt((49613.640304398235 / (299)) + (19067.83339047732 / (49))) is greater than 1.9668438982061167 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (49) - 2, .975) and 0.07163599096829677 = (8655.930140996192 - 8035.854007593581) / 8655.930140996192 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
