Yes, you're absolutely right. I apologize for this copy-paste mistake. It's fixed now.

I wonder if they swapped the benchmark results somehow. Because on my computer, I get roughly the same times but with {} twice as fast as dict().

Damb am I happy you commented this! I saw the same, checked it twice, and a final time before posting. But then the results were suddenly as expected (dict() being slower). At least I am not going mad, he must have changed it just now.
