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 2.825946273965538 < 3.519993971272723.
IsChangePoint: Marked as a change because one of 1/25/2022 6:54:35 PM, 2/1/2022 5:51:01 AM falls between 1/23/2022 2:39:24 PM and 2/1/2022 5:51:01 AM.
IsImprovementStdDev: Marked as improvement because 53.60215604347779 (T) = (0 -2851.434958798633) / Math.Sqrt((10040.369895231981 / (299)) + (9902.913318823703 / (44))) is greater than 1.9669451293272056 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (44) - 2, .975) and 0.23214154886261776 = (3713.4903634582324 - 2851.434958798633) / 3713.4903634582324 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
