My biggest beef had that they frequently choose recipes that would mask the differences. For example, looking at late boil hop additions vs flameout or whirlpool additions with respect to IBUs. The have a recipe with 3 oz of hops. With people routinely putting 6-8 oz of whirlpool hops in a NEIPA, their recipe isn't likely to really highlight the differences.
Are you referring to Kettle Hop vs. Hop Stand?
If so, I found this article interesting from a different perspective: a 'short and shoddy' Pale Ale - throw all the hops in at the end of the boil and let the kettle sit for a while:
...
To evaluate the differences between a Pale Ale hopped at various points during the boil and one where all hops were added at flameout for a 20 minute hop stand.
...
participants were unable to reliably distinguish a Pale Ale hopped that was hopped at multiple points during the boil from one where all of the hops were added at flameout and steeped for 23 minutes
...
What's also interesting in this article is that they used current recipe software to estimate IBUs and had the IBUs measured in a lab.
