### Description of detection logic
```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.
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 2.5909810096153842 > 2.398710526785714.
IsChangePoint: Marked as a change because one of 1/5/2023 12:24:13 PM, 1/18/2023 6:24:13 PM, 1/24/2023 6:33:57 AM falls between 1/15/2023 4:08:29 PM and 1/24/2023 6:33:57 AM.
IsRegressionStdDev: Marked as regression because -84.37075465607366 (T) = (0 -2606824.4042473733) / Math.Sqrt((375971267.4352063 / (36)) + (132841654.53033343 / (33))) is less than -1.9960083540247138 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (36) + (33) - 2, .025) and -0.1403969699018354 = (2285892.0823612562 - 2606824.4042473733) / 2285892.0823612562 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.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
