```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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 3/22/2022 12:26:23 PM, 4/4/2022 9:46:30 AM falls between 3/22/2022 12:26:23 PM and 4/4/2022 9:46:30 AM.
IsImprovementStdDev: Marked as improvement because 29.04017056706458 (T) = (0 -18.330036449252802) / Math.Sqrt((1.1336357181924002 / (299)) + (0.27721100173795876 / (16))) is greater than 1.9675720194858106 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (16) - 2, .975) and 0.18714077678804766 = (22.5500750016996 - 18.330036449252802) / 22.5500750016996 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
