```
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 37.80708944174757 > 11.645339269313274.
IsChangePoint: Marked as a change because one of 2/1/2023 12:50:52 AM, 3/1/2023 3:09:21 PM, 3/2/2023 11:15:04 AM, 3/29/2023 4:47:17 AM, 3/30/2023 4:24:24 AM falls between 3/21/2023 12:39:01 PM and 3/30/2023 4:24:24 AM.
IsRegressionStdDev: Marked as regression because -166.19403567937448 (T) = (0 -37931.75583022223) / Math.Sqrt((897967.1639334555 / (52)) + (38925.36634265819 / (5))) is less than -2.0040447832881556 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (52) + (5) - 2, .025) and -2.2626719923558443 = (11625.978927422992 - 37931.75583022223) / 11625.978927422992 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.
