Description of detection logic

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 28.72812992036764 > 25.155975108452218.
IsChangePoint: Marked as a change because one of 12/8/2022 3:49:24 AM, 12/15/2022 5:36:17 AM falls between 12/6/2022 5:26:30 PM and 12/15/2022 5:36:17 AM.
IsRegressionStdDev: Marked as regression because -29.31866380636942 (T) = (0 -28.742348406614948) / Math.Sqrt((0.23836008847915044 / (12)) + (0.14749418408835707 / (23))) is less than -2.034515297446192 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (12) + (23) - 2, .025) and -0.19810613652722506 = (23.989818205861283 - 28.742348406614948) / 23.989818205861283 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.
