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 10.473597322427294 < 11.686823588137418.
IsChangePoint: Marked as a change because one of 2/7/2022 2:49:00 PM, 2/23/2022 5:12:02 AM, 3/17/2022 6:54:53 PM, 3/29/2022 3:04:55 PM, 3/31/2022 1:45:25 PM falls between 3/22/2022 11:55:12 PM and 3/31/2022 1:45:25 PM.
IsImprovementStdDev: Marked as improvement because 15.957917112935995 (T) = (0 -10363.632805937707) / Math.Sqrt((670724.7055306466 / (299)) + (10007.709413730605 / (7))) is greater than 1.9677981407170237 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (7) - 2, .975) and 0.0853536142996128 = (11330.753576423736 - 10363.632805937707) / 11330.753576423736 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
