So the older/well circulated article that this author complains about would be describing Van Jacobson's algorithm?

Am I missing something about what the author is saying about the empirical data?

The stark uniformity of the empirical data up to the congestion threshold compared to the wild variance in heavier traffic is exactly the point of the older article this author is critiquing. Of course congestion happens when you approach capacity. This article is rejecting the original's explanation of that variance, without offering any new explanation.
