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 15.851948933333333 < 36.945464193769226.
IsChangePoint: Marked as a change because one of 7/4/2022 6:59:29 AM, 7/5/2022 7:51:46 PM, 7/14/2022 8:56:55 AM falls between 7/5/2022 7:51:46 PM and 7/14/2022 8:56:55 AM.
IsImprovementStdDev: Marked as improvement because 5.0909331864852225 (T) = (0 -15609.833598921114) / Math.Sqrt((9849245.872729292 / (299)) + (835128.8470480344 / (37))) is greater than 1.9670919629190173 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (37) - 2, .975) and 0.07135753139965346 = (16809.304039743427 - 15609.833598921114) / 16809.304039743427 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
