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 5.362898845170793 < 10.934307283211755.
IsChangePoint: Marked as a change because one of 3/13/2023 2:14:21 PM, 3/16/2023 2:30:29 AM falls between 3/7/2023 7:00:18 AM and 3/16/2023 2:30:29 AM.
IsImprovementStdDev: Marked as improvement because 38.83113353015142 (T) = (0 -5.913539769929361) / Math.Sqrt((0.8305443285585002 / (299)) + (0.1692995344467081 / (8))) is greater than 1.967772354556772 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (8) - 2, .975) and 0.5039697290711114 = (11.92173162911086 - 5.913539769929361) / 11.92173162911086 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
