I came upon your post because, like you, I was trying to get statistics.Other than a bare number of the total certified individuals, they don't give out breakdowns.
I'm thinking about taking 1Z0-055: 9i to 11g Upgrade. What you said about how hard the upgrade exams are isn't encouraging!Upgrade exams are 'different' than most. I don't know that I'd call them harder. The subject matter is extremely broad which can lead to increased study time. However, because of the broad scope, the depth of knowledge required by the questions tend to be shallow. You generally need to know what new features exist, why they were added, how they add to the functionality of the database, and possibly how to implement them. Because new features can (and do) come in many different sections of the database, the information is spread all through the documentation rather than being focused in one or two manuals. The total number of objectives listed by Oracle Education tends to be comparable to other tests. However, whereas an exam like 1Z0-146 send to have a topic area and 3-5 objectives that drill into that area, the specific objectives on upgrade tests are generally only loosely related... if at all.

Actually, several of the people in that thread who were against certs were (and still are) functioning at a very high level.
