I had a physics professor who used to drill into us during our labs that, "a number without an error estimate is meaningless." I didn't really get it at the time, and thought he was just being curmudgeonly. Now I understand how important it is. What's the error in these tests? The standard deviation? What was done to limit the error? It's great to see people putting numbers behind their claims, but let's get some real science back into computer science and do some serious data analysis.
