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 34.725284946986605 < 37.15445698974317.
IsChangePoint: Marked as a change because one of 6/20/2022 11:14:52 PM, 7/8/2022 12:50:30 PM, 7/12/2022 6:44:07 AM falls between 7/3/2022 4:26:07 AM and 7/12/2022 6:44:07 AM.
IsImprovementStdDev: Marked as improvement because 24.84043450162248 (T) = (0 -35699.34748865686) / Math.Sqrt((1962353.1671452841 / (299)) + (611699.4591567933 / (24))) is greater than 1.967381707010986 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (24) - 2, .975) and 0.11077192298398024 = (40146.44657696039 - 35699.34748865686) / 40146.44657696039 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
