That probably makes no sense....

Yeah that's the basic idea, if the overflow is too small water will rise above it to the point the majority of the water is taken from below the surface. However I don't think we run that kind of flow rate in our tanks to create such an effect with a single overflow. There's a limit to how small you can make it as well as a limit on how big, however for simplicity I can see how the bigger is always better principal is often applied not only to this but other applications as well. I'm just saying this isn't necessarily that accurate.
