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 549.1666333571428 > 524.886013701923.
IsChangePoint: Marked as a change because one of 5/11/2022 3:41:15 PM, 5/23/2022 7:50:08 PM, 5/31/2022 8:51:40 AM falls between 5/22/2022 6:37:49 PM and 5/31/2022 8:51:40 AM.
IsRegressionStdDev: Marked as regression because -37.70093537079637 (T) = (0 -542560725.8514153) / Math.Sqrt((15605936918299.818 / (22)) + (16830177370995.5 / (44))) is less than -1.997729654317006 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (22) + (44) - 2, .025) and -0.07829339964985865 = (503166138.2955646 - 542560725.8514153) / 503166138.2955646 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.

Perf has since recovered.

Likely #69291 exposed it a latent issue introduced by #68869 that was fixed by #70144. So going to close this one.
