```
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 0.056603940006034824 < 3.498153188086694.
IsChangePoint: Marked as a change because one of 3/21/2023 2:53:21 PM, 4/17/2023 5:51:51 AM, 4/25/2023 6:51:20 AM falls between 4/12/2023 8:39:35 PM and 4/25/2023 6:51:20 AM.
IsImprovementStdDev: Marked as improvement because 60.3109719210998 (T) = (0 -0.05819943802171456) / Math.Sqrt((2.758125742944672 / (299)) + (0.03756973721826034 / (27))) is greater than 1.9673127716992511 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (27) - 2, .975) and 0.9907211531635964 = (6.272270579290177 - 0.05819943802171456) / 6.272270579290177 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

```
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 1.2790505436285644 < 1.956187444291914.
IsChangePoint: Marked as a change because one of 1/5/2023 4:05:11 PM, 4/12/2023 6:21:10 AM, 4/17/2023 5:51:51 AM, 4/25/2023 6:51:20 AM falls between 4/12/2023 8:39:35 PM and 4/25/2023 6:51:20 AM.
IsImprovementStdDev: Marked as improvement because 54.59894756296223 (T) = (0 -1287.6953002745709) / Math.Sqrt((66369.40623817203 / (299)) + (72.9160589499582 / (27))) is greater than 1.9673127716992511 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (27) - 2, .975) and 0.3885825664026133 = (2106.0820799599696 - 1287.6953002745709) / 2106.0820799599696 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
