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 11.65017900561871 < 13.46977920904292.
IsChangePoint: Marked as a change because one of 5/11/2022 7:02:26 PM, 6/6/2022 7:24:37 AM, 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 9.859671652851054 (T) = (0 -12.129525137218051) / Math.Sqrt((0.4506565654045742 / (299)) + (0.2702973262610481 / (6))) is greater than 1.967824097752068 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (6) - 2, .975) and 0.14922008677407358 = (14.256948182081763 - 12.129525137218051) / 14.256948182081763 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
