Description of detection logic

IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed: Marked as improvement because 0 < 7.987085521246584.
IsChangePoint: Marked as a change because one of 3/6/2023 4:48:38 PM, 5/30/2023 10:12:23 PM, 6/5/2023 10:09:45 PM falls between 5/27/2023 6:38:16 PM and 6/5/2023 10:09:45 PM.
IsImprovementStdDev: Marked as improvement because 98.44314589443968 (T) = (0 -0) / Math.Sqrt((2.6860258081846933 / (299)) + (0 / (20))) is greater than 1.9674756580274855 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (20) - 2, .975) and 1 = (9.33050135327891 - 0) / 9.33050135327891 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

@kg could that be dotnet/runtime#86403 or is the measurement broken? :-)

[kg]

These two benchmarks appear to have started crashing. I'm not sure why that reports as a 0 and is an "improvement" :)

[kg]

Should be fixed by dotnet/runtime#87246. We should look into whether we can detect crashed wasm benchmarks and surface them as something other than "improvements" :)
