... derp, yes. It was way too early in the morning, and I misread "is part of the benchmark" as "is not part of the benchmark"...

In your defense, the "use it for data initializing" suggestion isn't exactly helpful text either.

Also, for the record: I presume you tested on Chrome, but on Firefox the difference between the two loop styles is quite a bit larger (and generally slower than Chrome, so perhaps also a consideration when optimizing for "slowest browser" as the bottleneck).
