Has this kind of test been repeated by independent researchers? It seems like this kind of test is amazingly easy to fiddle by simply messing with the simulated browsing behaviour, and big companies have fiddled benchmarks before. It also doesn't help that this is precisely the perfect result for them, with their strongest competitor coming out worst.
Note: Opera has already fired back with a test of their own, but that's still not really independent.
