Description of detection logic

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.
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 we could not find enough baseline builds for window checking.
IsChangePoint: Marked as a change because one of 5/19/2023 4:22:12 AM, 5/31/2023 10:16:51 PM, 6/7/2023 7:43:49 PM falls between 5/29/2023 11:58:32 PM and 6/7/2023 7:43:49 PM.
IsImprovementStdDev: Marked as improvement because 22.97522886572232 (T) = (0 -195.8057616019428) / Math.Sqrt((13.885115106338915 / (299)) + (6.4603274230276435 / (12))) is greater than 1.9676708853560316 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (12) - 2, .975) and 0.08234150976620605 = (213.3754154577232 - 195.8057616019428) / 213.3754154577232 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
