If you understand the problem well enough that you know that the frequency of errors is stable and won’t blow up on out-of-sample data, then it seems like you’ve fully modeled what’s happening? That’s not any easier than solving the problem because it is solving the problem.
If don’t have good reasons to be confident that the error rate is stable, then you’re just guessing that you solved the problem, because it seems to work.
