Nothing to see here. Author uses Octane benchmark where bigger is better, so v8 ~26 beats the "experimental engine".
Q: What do the scores mean?
A: In a nutshell: bigger is better. Octane measures the time a test takes to complete and then assigns a score that is inversely proportional to the run time (historically, Firefox 2 produced a score of 100 on an old benchmark rig the V8 team used).
