I am not sure that the ambiguity has to work that way. The suggestion I am making is that if we fix the distribution on questions and the training data, we might (a) know the value of X in this specific case, (b) be able to ensure that it is fairly high. I’d say this is the murky case because on the fixed training data and query distribution X ≈ 1 and we know that even though we don’t know the value of X on other training data and other query distributions. I think that might be where the disagreement lies.
