Let us know when you have Qwen vs Qwen comparison stats. As long as there's not a regression, that'd be awesome.
4% is within the margin of error anyways for pass@1, so I think pass@k > 1 is gonna be the better indicator of any movement (still need to calibrate the optimal k to re-test). 10 seems too tolerant even though that tends to be the next tranche I reach for.
