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 577.3352489409804 < 757.5383343168422.
IsChangePoint: Marked as a change because one of 7/2/2022 7:35:06 PM, 7/6/2022 3:55:24 AM, 8/24/2022 2:39:26 AM, 8/30/2022 4:40:43 AM falls between 8/21/2022 6:52:55 AM and 8/30/2022 4:40:43 AM.
IsImprovementStdDev: Marked as improvement because 2443.7052040597127 (T) = (0 -577.6763708550544) / Math.Sqrt((0.7595593448077305 / (299)) + (0.1785246461208641 / (32))) is greater than 1.9672006833568965 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (32) - 2, .975) and 0.27597747720140176 = (797.8707190242299 - 577.6763708550544) / 797.8707190242299 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
