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 162.09594105484888 < 194.89290742685162.
IsChangePoint: Marked as a change because one of 6/23/2022 3:07:42 AM, 7/2/2022 7:35:06 PM, 7/6/2022 3:55:24 AM, 8/17/2022 2:19:52 AM, 8/25/2022 6:55:57 AM falls between 8/16/2022 2:19:13 PM and 8/25/2022 6:55:57 AM.
IsImprovementStdDev: Marked as improvement because 12.026076496812836 (T) = (0 -162.10850846051417) / Math.Sqrt((738.9079754278956 / (299)) + (411.9357131065255 / (35))) is greater than 1.9671350567190904 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (35) - 2, .975) and 0.21872173454601251 = (207.49138383660997 - 162.10850846051417) / 207.49138383660997 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
