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 297.6709341236771 > 276.9819006858682.
IsChangePoint: Marked as a change because one of 5/31/2022 5:02:26 PM, 6/9/2022 4:58:43 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 4:58:43 AM.
IsRegressionStdDev: Marked as regression because -5.7326841542386395 (T) = (0 -311.8049826288513) / Math.Sqrt((280.8213364247804 / (11)) + (719.7321643610898 / (34))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (11) + (34) - 2, .025) and -0.1436918839458107 = (272.63023110132076 - 311.8049826288513) / 272.63023110132076 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.

First was resolved in 2d5c8dc
Second was mostly fixed but still has a small regression related to #70182
