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 18.02399817244539 < 21.33225845531853.
IsChangePoint: Marked as a change because one of 2/19/2022 11:51:48 PM, 3/28/2022 7:37:41 AM, 4/16/2022 10:12:41 PM, 4/19/2022 4:39:14 PM falls between 4/10/2022 11:44:05 PM and 4/19/2022 4:39:14 PM.
IsImprovementStdDev: Marked as improvement because 6.86758911103839 (T) = (0 -18.33085700306141) / Math.Sqrt((2.1115357499303005 / (299)) + (1.0417401932245534 / (9))) is greater than 1.9677467375895035 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (9) - 2, .975) and 0.1160553268050995 = (20.737561477470038 - 18.33085700306141) / 20.737561477470038 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
