Yeah, more sophisticated and challenging experiments can be had. However, as they say, reality is relative. If the tests they ran are "realistic" in the sense that most people use the systems in the same way they tested, then it's all good. I suppose we need to agree on what's realistic / acceptable. I would say just minimize client-server RTT and that's a good setup, which they may have.
