progresses = np.array([(avg >= 40) and (hard_fail == 0) for (avg, soft_fail, hard_fail) in results])

Python loops are slow. It is expected something like this:

progresses = results[(results[:, 0] >= results[:, 0].mean()) * (results[:, 2] != 0)]

or

progresses = results[(results[:, 0] >= 40) * (results[:, 2] != 0)]
