I'm curious what the article is referring to when it comes to collision resistance. I was looking at the GitHub repo posted below and saw only claims of "strong" collision resistance: https://github.com/google/highwayhash

Unfortunately I'm not familiar enough with the details of the collision resistance properties of the other hash functions here to know how they compare. Could someone elaborate on the specifics of why HighwayHash compares poorly in terms of collision resistance to the others in the benchmark?
