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 1.2352082764543946 < 444.26072796658985.
IsChangePoint: Marked as a change because one of 2/14/2022 7:55:17 PM, 2/22/2022 12:12:47 AM falls between 2/13/2022 12:11:49 PM and 2/22/2022 12:12:47 AM.
IsImprovementStdDev: Marked as improvement because 1559.916477247883 (T) = (0 -1226.7591048688607) / Math.Sqrt((1977793.118720342 / (22)) + (685.1060583432597 / (46))) is greater than 1.9965644189515825 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (22) + (46) - 2, .975) and 0.9973841950072655 = (468979.57159506157 - 1226.7591048688607) / 468979.57159506157 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
