Description of detection logic

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 55.31028243106316 < 59.452037497985685.
IsChangePoint: Marked as a change because one of 12/26/2021 4:30:45 AM, 2/23/2022 1:54:47 PM, 3/1/2022 7:31:17 PM, 4/29/2022 11:03:27 PM, 5/5/2022 2:36:12 AM falls between 4/26/2022 10:28:11 AM and 5/5/2022 2:36:12 AM.
IsImprovementStdDev: Marked as improvement because 8.81628149270319 (T) = (0 -57.059137543416504) / Math.Sqrt((7.336418188999802 / (299)) + (10.876227064396673 / (19))) is greater than 1.9674995188240387 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (19) - 2, .975) and 0.1066493650352127 = (63.87093187174549 - 57.059137543416504) / 63.87093187174549 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
