Yeah I've had a difficult time figuring out how this was tested:

I would recommend using the benchmark at https://github.com/v8/web-tooling-benchmark in the future if it's currently not possible since currently it only seems to be testing ES5 (jquery.min.js) for the parser and a short ES6 snippet for the transforms.

(I think when you say "tested" you mean "benchmarked" – your comment at https://news.ycombinator.com/item?id=18746905 gave a nice link to how it is tested).
