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 3/18/2022 1:59:24 AM, 5/23/2022 7:50:08 PM, 5/26/2022 4:44:18 AM falls between 5/17/2022 2:28:28 PM and 5/26/2022 4:44:18 AM.
IsImprovementStdDev: Marked as improvement because 17.50106479531735 (T) = (0 -2943.2589867583497) / Math.Sqrt((15182.522024665363 / (299)) + (4868.750217447951 / (9))) is greater than 1.9677467375895035 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (9) - 2, .975) and 0.1263671144177743 = (3368.9883191574663 - 2943.2589867583497) / 3368.9883191574663 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
