### 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 962.1043680354613 < 1.044697846519542.
IsChangePoint: Marked as a change because one of 3/23/2022 6:35:24 PM, 4/29/2022 5:18:09 PM, 5/3/2022 11:42:39 AM falls between 4/24/2022 10:52:31 PM and 5/3/2022 11:42:39 AM.
IsImprovementStdDev: Marked as improvement because 48.396406007657696 (T) = (0 -957.1164489746607) / Math.Sqrt((1460.0355333901807 / (299)) + (67.40692785121085 / (18))) is greater than 1.9675235316906419 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (18) - 2, .975) and 0.1293183243302673 = (1099.272530616246 - 957.1164489746607) / 1099.272530616246 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
