Javascript Benchmarks — what?

I installed a beta version of the Google Chrome browser for Mac the other day. I forget just where I found it, but it was probably linked from something linked from MacHeist which Charley mentioned on his blog. At any rate, while looking through the Help page I ran across a page of Javascript benchmarks.

The latest Safari, which I just downloaded from Apple Software Update, 4.0.4 (5531.21.10) has

Does that mean that Chrome is about half again as fast at processing Javascript as Safari, and ten times as fast as Firefox??
