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 11.447133976924233 < 12.66399954834874.
IsChangePoint: Marked as a change because one of 1/11/2023 2:37:52 AM, 1/17/2023 2:54:07 AM falls between 1/8/2023 8:00:22 AM and 1/17/2023 2:54:07 AM.
IsImprovementStdDev: Marked as improvement because 53.38146707338493 (T) = (0 -11.274653866839044) / Math.Sqrt((0.16071153420831377 / (299)) + (0.0350613953884214 / (29))) is greater than 1.9672675222597202 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (29) - 2, .975) and 0.165182622440484 = (13.505533269802172 - 11.274653866839044) / 13.505533269802172 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

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 8.906619437036996 < 10.886026672379161.
IsChangePoint: Marked as a change because one of 1/11/2023 2:37:52 AM, 1/17/2023 2:54:07 AM falls between 1/8/2023 8:00:22 AM and 1/17/2023 2:54:07 AM.
IsImprovementStdDev: Marked as improvement because 61.14887673705184 (T) = (0 -9.074354564835483) / Math.Sqrt((0.05117427642134022 / (299)) + (0.028276804578522673 / (29))) is greater than 1.9672675222597202 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (29) - 2, .975) and 0.18576200568639464 = (11.144597314554296 - 9.074354564835483) / 11.144597314554296 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

IsChangePoint: Marked as a change because one of 11/2/2022 9:35:40 AM, 1/11/2023 2:37:52 AM, 1/17/2023 2:54:07 AM falls between 1/8/2023 8:00:22 AM and 1/17/2023 2:54:07 AM.
IsImprovementStdDev: Marked as improvement because 101.09874240861828 (T) = (0 -8143.710210479142) / Math.Sqrt((63454.23720547872 / (299)) + (41379.16596858862 / (29))) is greater than 1.9672675222597202 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (29) - 2, .975) and 0.3344880520766503 = (12236.760340502697 - 8143.710210479142) / 12236.760340502697 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
