alt Hacker News4% 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.
Depends on where you sit on the binomial curve. At p=0.04 for n=250 4% points would not be within margin of error.
