### 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 0.41554966749792194 < 93.83807229564495.
IsChangePoint: Marked as a change because one of 2/1/2023 6:25:50 PM, 2/7/2023 8:22:47 AM falls between 1/29/2023 5:12:48 PM and 2/7/2023 8:22:47 AM.
IsImprovementStdDev: Marked as improvement because 19.14563224930208 (T) = (0 -8.044389046831002) / Math.Sqrt((6.152758043534185 / (299)) + (648.2752030230442 / (29))) is greater than 1.9672675222597202 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (29) - 2, .975) and 0.9184199170774386 = (98.60726734571979 - 8.044389046831002) / 98.60726734571979 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
