The exercise was more about evaluating what the tool could bring for already-optimized code than about comparing the results against what an expert programmer could achieve manually.

It is true that the application domain of the code chosen for the blog post might be a bit unfortunate in order to make a realistic case. Game engine programmers are usually very good at low level optimizations. Pareon can be used by non-experts though and additionally assist experts in during the task of finding and applying optimizations and paralellization oportunities.

Quoting the blog update [1]:

"Our Pareon tool is not aimed to replace parallelization experts. We want the tool to be useful for any programmer who is looking for paralellization opportunities in either his own code or in code that he is unfamiliar with. A domain expert (game programmer) can probably save some time because of his in-depth knowledge."

Additionally:

"The three additional cores on my four-core machine are only used during part of a rendering cycle. They are sleeping the rest of the time. If I would parallelize other pieces of code in the cycle as well, it would increase utilization and I would expect the frame rate to improve even more."
