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 30.604488815038785 < 39.5979672886658.
IsChangePoint: Marked as a change because one of 7/2/2022 7:35:06 PM, 7/6/2022 3:55:24 AM, 9/10/2022 4:15:15 AM, 9/15/2022 1:10:12 AM falls between 9/6/2022 1:06:44 PM and 9/15/2022 1:10:12 AM.
IsImprovementStdDev: Marked as improvement because 30.575890341781125 (T) = (0 -31.5376696509886) / Math.Sqrt((41.43916454591057 / (299)) + (0.2869576743040724 / (21))) is greater than 1.967451947860886 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (21) - 2, .975) and 0.2744694902592944 = (43.46842652042258 - 31.5376696509886) / 43.46842652042258 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
