I think there is more to it than a desire to space the releases to get better PR.
They may want to verify the authenticity of the documents to avoid fake leaks. They may also want to edit some documents to remove data that would put individual persons at risk, like they did with Cablegate.
Doing this takes time, and may not be short-circuited easily.
They can't simply encrypt the files, release them using P2P, and then edit them / check them for authenticity. I guess it would be useful as an insurance, though.
