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 29.745970644173973 < 30.579009425098956.
IsChangePoint: Marked as a change because one of 12/28/2022 5:13:50 PM, 1/3/2023 6:29:42 AM falls between 12/23/2022 9:40:21 PM and 1/3/2023 6:29:42 AM.
IsImprovementStdDev: Marked as improvement because 8.03377540262315 (T) = (0 -29.786236112966343) / Math.Sqrt((0.6142171521206813 / (299)) + (1.2209179767904108 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.07457292595103529 = (32.18647578857234 - 29.786236112966343) / 32.18647578857234 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 29.194004052835457 < 29.32247219066154.
IsChangePoint: Marked as a change because one of 10/31/2022 10:23:25 PM, 12/28/2022 5:13:50 PM, 1/3/2023 6:29:42 AM falls between 12/23/2022 9:40:21 PM and 1/3/2023 6:29:42 AM.
IsImprovementStdDev: Marked as improvement because 14.512061347326483 (T) = (0 -29.236423889734663) / Math.Sqrt((3.323298949304289 / (299)) + (0.06780201896632884 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.05900355398482968 = (31.069643263310823 - 29.236423889734663) / 31.069643263310823 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 385.7844543650793 < 416.3832572337962.
IsChangePoint: Marked as a change because one of 11/18/2022 8:48:12 PM, 12/17/2022 10:44:50 PM, 12/28/2022 5:13:50 PM, 1/3/2023 6:29:42 AM falls between 12/23/2022 9:40:21 PM and 1/3/2023 6:29:42 AM.
IsImprovementStdDev: Marked as improvement because 15.787190690987147 (T) = (0 -383826.62622452434) / Math.Sqrt((448854648.7871664 / (299)) + (3719204.32425675 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.05183835249080365 = (404811.381300678 - 383826.62622452434) / 404811.381300678 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 32.76973612871624 < 33.030895501781075.
IsChangePoint: Marked as a change because one of 12/28/2022 5:13:50 PM, 1/3/2023 6:29:42 AM falls between 12/23/2022 9:40:21 PM and 1/3/2023 6:29:42 AM.
IsImprovementStdDev: Marked as improvement because 38.481267995544115 (T) = (0 -32.78076698709662) / Math.Sqrt((0.204904688753246 / (299)) + (0.028475640986215304 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.05768374604111148 = (34.78743664812852 - 32.78076698709662) / 34.78743664812852 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 313.17282115735014 < 319.82714756498723.
IsChangePoint: Marked as a change because one of 11/7/2022 4:10:19 PM, 11/17/2022 7:01:39 PM, 12/28/2022 5:13:50 PM, 1/3/2023 6:29:42 AM falls between 12/23/2022 9:40:21 PM and 1/3/2023 6:29:42 AM.
IsImprovementStdDev: Marked as improvement because 8.922121740389377 (T) = (0 -311.4975207969216) / Math.Sqrt((113.52642790739384 / (299)) + (53.439177061771915 / (14))) is greater than 1.9676211333067681 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (14) - 2, .975) and 0.055425233636386476 = (329.77539935362915 - 311.4975207969216) / 329.77539935362915 is greater than 0.05.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.
