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 15.829495218029223 > 12.255039441035741.
IsChangePoint: Marked as a change because one of 3/22/2022 12:26:23 PM, 6/6/2022 8:15:49 PM, 6/9/2022 12:28:12 AM falls between 5/31/2022 10:47:41 AM and 6/9/2022 12:28:12 AM.
IsRegressionStdDev: Marked as regression because -9.159281745266673 (T) = (0 -18.97853846493613) / Math.Sqrt((1.4576871194799397 / (37)) + (4.132828696367864 / (8))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (37) + (8) - 2, .025) and -0.5621637043335346 = (12.148879411478157 - 18.97853846493613) / 12.148879411478157 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.

Milestone:	-

[tannergooding]

Retargeting to .NET 8. We're emitting an extra instruction here but its not something that's high priority to fix.

This is related to #70182 and #81766. Closing as it is better tracked by those issues.
