Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 42.64403723887376 > 41.74078027565193.
IsChangePoint: Marked as a change because one of 10/15/2021 6:13:58 AM, 10/30/2021 6:22:30 PM, 11/22/2021 3:34:51 PM, 11/23/2021 3:51:55 AM falls between 11/14/2021 12:07:47 PM and 11/23/2021 3:51:55 AM.
IsRegressionStdDev: Marked as regression because -42.731659966143916 (T) = (0 -42587.579647516584) / Math.Sqrt((110531.80176948766 / (57)) + (6374.9192437067595 / (2))) is less than -2.0024654592901125 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (57) + (2) - 2, .025) and -0.07740348069631754 = (39527.97666849244 - 42587.579647516584) / 39527.97666849244 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

Possibly dotnet/runtime#61882, but this test is flaky. Will look again next week.
