If there are limitations to scaling, they'll probably not spell them out in the papers either. It's unfortunate, but "negative" aspects of one's own results are strongly suppressed in scientific publishing. And I'm not in any way pointing the finger at these particular authors, I'm pretty sure they're excellent scientists, it's just a problem in general. I had a look around, and the papers aren't on any preprint servers etc. I guess we could violate copyrights, but a better solution might be that someone emails George and asks if she can get the preprints posted somewhere. Edit: there's a preprint of the 2015 paper here: http://opus.bath.ac.uk/44557/ http://opus.bath.ac.uk/44557/
