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 9.388504593569003 < 15.543874984460963.
IsChangePoint: Marked as a change because one of 5/31/2022 5:02:26 PM, 6/6/2022 8:15:49 PM, 7/7/2022 7:47:15 PM, 7/14/2022 8:56:55 AM falls between 7/5/2022 7:51:46 PM and 7/14/2022 8:56:55 AM.
IsImprovementStdDev: Marked as improvement because 47.540035172739024 (T) = (0 -9363.495879128612) / Math.Sqrt((8215053.626946585 / (299)) + (131.104905487259 / (27))) is greater than 1.9673127716992511 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (27) - 2, .975) and 0.457007476814515 = (17244.244587747413 - 9363.495879128612) / 17244.244587747413 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
