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 328.45712982669505 < 350.9517052776704.
IsChangePoint: Marked as a change because one of 5/1/2022 2:35:06 PM, 5/3/2022 11:42:39 AM falls between 4/24/2022 10:52:31 PM and 5/3/2022 11:42:39 AM.
IsImprovementStdDev: Marked as improvement because 16.167149076226625 (T) = (0 -319894.0033181775) / Math.Sqrt((445677901.4144119 / (299)) + (68030907.37077412 / (9))) is greater than 1.9677467375895035 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (9) - 2, .975) and 0.13197010138412515 = (368528.7843520914 - 319894.0033181775) / 368528.7843520914 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
