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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 12/8/2021 6:13:42 AM, 1/5/2022 4:19:16 PM falls between 12/6/2021 2:46:54 PM and 1/5/2022 4:19:16 PM.
IsImprovementStdDev: Marked as improvement because 51.19388625071951 (T) = (0 -2540.0058309556784) / Math.Sqrt((453724.90930214623 / (12)) + (655.4074044420927 / (142))) is greater than 1.975693927815077 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (12) + (142) - 2, .975) and 0.796721682665499 = (12495.212791318116 - 2540.0058309556784) / 12495.212791318116 is greater than 0.05.
IsChangeEdgeDetector: Marked as regression because Edge Detector said so.
