It is crummy that you can't read other peoples perf numbers, that being said, evaluation versions exist for a reason. No need to rely on other peoples generic benchmarks.
Not everyone has the expertise or the time to run their own extensive, comprehensive benchmark suite. It could be dangerous to do so for the uninitiated who may come to the wrong conclusions.
