Description of detection logic

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.
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 57.81001883378264 > 50.94067604705198.
IsChangePoint: Marked as a change because one of 5/19/2023 10:55:27 PM, 5/23/2023 2:36:40 AM falls between 5/14/2023 5:56:01 AM and 5/23/2023 2:36:40 AM.
IsRegressionStdDev: Marked as regression because -5.489857971637664 (T) = (0 -58.611300481951545) / Math.Sqrt((66.11167285007295 / (32)) + (1.2268756530650748 / (13))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (32) + (13) - 2, .025) and -0.15965055827950575 = (50.542208653707824 - 58.611300481951545) / 50.542208653707824 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.

This looks like dotnet/runtime#86481, it is quite small regression though.
