Hm, I think it's straightforward to follow the same pattern for the other RDD, but yes it's updated in enough places that it's a fair bit of extra code. It might be possible to refactor this nicely in some method. Not essential, maybe. This code isn't used much anyway. A partial improvement may be a sufficient win.
