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 58.15035935465465 < 59.32185255965126.
IsChangePoint: Marked as a change because one of 12/27/2021 12:37:17 AM, 4/30/2022 7:46:32 AM, 5/5/2022 2:36:12 AM falls between 4/26/2022 10:28:11 AM and 5/5/2022 2:36:12 AM.
IsImprovementStdDev: Marked as improvement because 6.393224729059906 (T) = (0 -59.704021104128515) / Math.Sqrt((13.562903735219638 / (299)) + (11.60612080402414 / (18))) is greater than 1.9675235316906419 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (18) - 2, .975) and 0.08169122568840433 = (65.01519181158348 - 59.704021104128515) / 65.01519181158348 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
