Yes, maybe he was. As I said though, that's not necessarily relevant to navigational practice. You can get a useful rate on a chronometer with any pair of longitude verifications and usually they will be separated by weeks. You're not getting the instantaneous rate, but it is a "practical" and useful rate, and the fact that it is an average rate may well make it more useful in practice instead of less useful.
