Well, what I said also goes for photons. Plus, there is no way to rule you
they didn't make some mistakes when running the benchmark. All I can really
say is that their reasoning that using a 64 bit compile creates "better" is
not based on any facts. It is certainly possible to make good guesses what
else might be wrong with their compile, but those don't really lead
anywhere, I am afraid.
