The problem is, no data about the actual hardware used. What video card, HD, RAM, etc. Any and all of these can schew benchmarks off by up to 30% in any direction, depending on the benchmark.
Heck, I remember a benchmark where the hardware was chosen specifically to cripple a particular OS for an OS 2 OS comparison, causing an artificial "boost" in the sponsoring company. That's why public disclosure of the hardware is so critical.
