This is the only actual breakdown that I've seen. The user with 50K SP under n^2 would allocate 0.9% of the STEEM that the 500K SP user would. With the linear algorithm, that same 50K SP user would allocate 9% of the STEEM that the 500K SP user would.

Of course, I don't know what numbers they're running, other than what is stated below. It would appear that allocation will be improved, but that doesn't necessarily mean that curation rewards would be. It depends on what's changed in the curation rewards algorithm. If they're aiming for similar results compared to how things are now, then I obviously wouldn't expect much to change.
