I understand those arguments, but it doesn't addresses the issue for a very specific reason. What if the problem is the way internally the team works? When measuring end-to-end, any part of that may influence the final outcome. If, and I am not saying this is true, if there is a tendency to have a few more errors (especially grammatical with it's its) in a non-native tongue, success outcomes MAY point to a bias in interviewing, or in how people interact internally. Or not. It is just something I wondered, and something it doesn't seem like you've looked at specifically, and understandably as well, because who wants to open themselves to accusations of bias with their own data?
