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 131.4886804216261 < 341.54028418897656.
IsChangePoint: Marked as a change because one of 11/17/2021 2:42:53 PM, 11/23/2021 6:42:08 AM falls between 11/14/2021 12:07:47 PM and 11/23/2021 6:42:08 AM.
IsImprovementStdDev: Marked as improvement because 233.01581990051722 (T) = (0 -134.62992588873942) / Math.Sqrt((21.187410416253712 / (299)) + (23.9733951124748 / (28))) is greater than 1.967290077109849 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (28) - 2, .975) and 0.6249716508504021 = (358.9859971760051 - 134.62992588873942) / 358.9859971760051 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
