Nicholas,

I never doubted the authenticity of the benchmark, nor the results. What I
think could be better is an objective analysis of the results. That post
neglected to point out the significant differences in hardware those two
benchmarks were run on. It is bit like bragging you broke the world record
at the Nürburgring in a 2014 1000hp LaFerrari and somehow forgetting to
mention that the last record was held by a 2001 Toyota Celica.
