FoldPipe reduces mean training pass time from 83.37 seconds to 76.78 seconds, though the geometric mean speedup of 1.059x has a wide confidence interval that includes values below 1.0x

Mean pass time is 76.78 s for FoldPipe and 83.37 s for the baseline. However, the geometric mean paired speedup is $1.059\times$ with a 95% bootstrap interval from $0.878\times$ to $1.288\times$.
