Calling this a "replication attempt" implied to me that they tried to replicate the Chinchilla Scaling paper and found that it did not replicate, which would be a very big deal!
Instead, they just redid the analysis based on a figure in the paper and found that the old model with slightly different parameters gave a better fit to the data. This is a valuable contribution, but a bit over-stated by the paper title, and the confrontational, "gotcha" tone of the paper is unwarranted.
A better framing would have been something like "Chinchilla Scaling: Reanalyzed".
