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 25.621391936001302 < 26.701411064078084.
IsChangePoint: Marked as a change because one of 3/23/2022 10:40:09 PM, 3/31/2022 1:45:25 PM falls between 3/22/2022 11:55:12 PM and 3/31/2022 1:45:25 PM.
IsImprovementStdDev: Marked as improvement because 26.937109174957055 (T) = (0 -25.412631297336418) / Math.Sqrt((0.2871288106378486 / (299)) + (0.38723362664035127 / (32))) is greater than 1.9672006833568965 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (32) - 2, .975) and 0.10805246049606042 = (28.491172599085548 - 25.412631297336418) / 28.491172599085548 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
