As for correctness, we've only done mAP scores and traditional accuracy metrics so far to compare with other algorithms, but we also have our own internal metrics and a test set we're building out in-house to cover many edge cases, many of which cover some of the things you are talking about. One thing we're always trying to be sensitive of is fairness. We want to make sure that we're not biasing the test to our algorithm, which would make us look better than we are.
