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 844.2070543857026 < 0.9737194090365708.
IsChangePoint: Marked as a change because one of 3/21/2023 3:33:39 AM, 3/23/2023 3:52:33 AM falls between 3/14/2023 3:18:57 PM and 3/23/2023 3:52:33 AM.
IsImprovementStdDev: Marked as improvement because 6.14845006495606 (T) = (0 -854.9979936002677) / Math.Sqrt((3527.130514474469 / (251)) + (2500.3592791477977 / (5))) is greater than 1.9693475402190106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (251) + (5) - 2, .975) and 0.14019555681372978 = (994.4098339755134 - 854.9979936002677) / 994.4098339755134 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
