Correct in certain circumstances but not always, more often than not a single large pump is more efficient than multiple smaller pumps.

But again yes it's how you look at it, my main point was there are certainly advantages but that's not to say there aren't disadvantages as well. None of the advantages I listed related to efficiency and that's mostly because efficiency is closely tied to money.
