I've only browsed the source, but I think it's more likely that most of the results are random noise, and there's no particular reason why one case is faster than the other. There are a ton of things one needs to do to make reliable microbenchmarks (make sure the functions are getting optimized, make sure they're not eliminated as dead code, etc.) and I don't think this repo does any of them.
