Pretty obviously he did not. As it says in the article, he ran just this test, and while you can't infer too much from a single test, it certainly sets the stage for the upcoming shootout.

I wouldn't say pretty obviously. He never said he just ran this test, he said that this is the result from just one test.

I'm just curious if this is a cherry-picked result or truly the only test he ran.

Cherry-picked or not, the results are very impressive.

Edit:

After reading again he states he chose this specific test "because it’s the first test" (from the Computer Language Benchmarks Game) does make more sense to me. It just seemed like an odd choice to use for a sole test.

(His name is Antonio, not Anthony, just as your name is ... well, you have no name or contact or anything in your profile, so we'll say your name is 'icey', and not 'ghiacciato')

Ah, point well made. If I could still edit my other post, I would.
