Why do mislabeled dev set examples become more impactful as a classifier improves?

It is acceptable to initially tolerate mislabeled dev/test examples and reconsider that decision as the system improves.

When mislabeled dev examples account for _____ of all errors, improving dev-set label quality becomes worthwhile.

Match each scenario to its correct implication regarding mislabeled dev set examples.

Order the reasoning steps for deciding whether to invest in fixing mislabeled dev set labels.
