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.
IsRegressionWindowed: Marked as regression because 1.030416603635204 > 957.5054441406253.
IsChangePoint: Marked as a change because one of 9/1/2022 8:04:48 PM, 10/31/2022 10:23:25 PM, 11/10/2022 12:29:27 AM, 11/14/2022 7:25:10 PM falls between 11/5/2022 10:22:58 PM and 11/14/2022 7:25:10 PM.
IsRegressionStdDev: Marked as regression because -10.422654394442336 (T) = (0 -1040483.2927333609) / Math.Sqrt((1247047688.9220223 / (31)) + (847391010.076601 / (23))) is less than -2.0066468050606243 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (31) + (23) - 2, .025) and -0.09641925640305421 = (948983.0524746542 - 1040483.2927333609) / 948983.0524746542 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

This is probably noise but could potentially have been caused by dotnet/runtime#77872. @BruceForstall thoughts?

That change would only affect how fast the JIT runs, not the generated code, and BDN should only measure the generated code.

Seems fairly stable to me
