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 398.585961269036 < 1.3731261070336664.
IsChangePoint: Marked as a change because one of 7/10/2022 3:20:59 AM, 7/18/2022 2:17:16 AM falls between 7/8/2022 10:31:34 AM and 7/18/2022 2:17:16 AM.
IsImprovementStdDev: Marked as improvement because 721.3016917455001 (T) = (0 -401.418944463478) / Math.Sqrt((65.01691921369166 / (299)) + (97.07028271584421 / (52))) is greater than 1.9667845565748345 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (52) - 2, .975) and 0.7217664181703665 = (1442.740814476064 - 401.418944463478) / 1442.740814476064 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
