I found it really refreshing that they report a bunch of stuff they tried that didn’t work in a way that clarifies the problem and leads to a lot of insight into the strengths and limitations of their final method and the leading alternatives
You're welcome! There is a talk too [1], which is how I had learned about the paper.
