### 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 20.367052147941074 < 25.28777589370507.
IsChangePoint: Marked as a change because one of 11/22/2021 6:45:42 PM, 1/20/2022 9:28:17 PM, 1/31/2022 1:37:35 PM, 2/2/2022 11:04:24 PM falls between 1/25/2022 5:49:56 AM and 2/2/2022 11:04:24 PM.
IsImprovementStdDev: Marked as improvement because 52.37093008835673 (T) = (0 -19.962086122037054) / Math.Sqrt((0.8356211589963407 / (299)) + (0.17278816585848109 / (9))) is greater than 1.9677467375895035 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (9) - 2, .975) and 0.2800951988931682 = (27.72878593300941 - 19.962086122037054) / 27.72878593300941 is greater than 0.05.
