System.Text.RegularExpressions.Tests.Perf_Regex_Industry_Leipzig.Count(Pattern: "[a-z]shing", Options: NonBacktracking)

Description of detection logic

IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionWindowed: Marked as regression because 4.261496722906404 > 4.186219621173835.
IsChangePoint: Marked as a change because one of 9/21/2022 4:00:51 AM, 11/1/2022 8:41:52 AM, 11/2/2022 9:17:08 PM falls between 10/25/2022 8:54:59 AM and 11/2/2022 9:17:08 PM.
IsRegressionStdDev: Marked as regression because -19.023960774800585 (T) = (0 -4224288.072663577) / Math.Sqrt((1310592089.307382 / (39)) + (514359727.05005777 / (6))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (39) + (6) - 2, .025) and -0.05174087916626889 = (4016472.266450492 - 4224288.072663577) / 4016472.266450492 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
