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.

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because we could not find enough baseline builds for window checking.

                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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 5/26/2023 6:22:05 AM, 7/5/2023 7:07:19 PM, 7/12/2023 2:12:47 AM, 7/23/2023 4:13:29 AM, 8/17/2023 8:30:03 PM, 8/21/2023 10:38:45 PM falls between 8/13/2023 2:50:54 AM and 8/21/2023 10:38:45 PM.
IsRegressionStdDev: Marked as regression because -23.32740069882594 (T) = (0 -24437.675796408497) / Math.Sqrt((902218.3064969234 / (9)) + (46976.70673320098 / (10))) is less than -2.109815577813699 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (9) + (10) - 2, .025) and -0.4476657453529143 = (16880.744657290375 - 24437.675796408497) / 16880.744657290375 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.
