You are aware that the days figure is the total time at the current
rate, and not the remaining time right?
ie: it's totalObjects/rate, not (totalObjects - uploadedObjects)/rate

The reason I ask is that the completion date quoted on the stats page
is 9th June, which is now + 262 days... which is about 22 days more
than it should be if you take into account the 32m objects already

The completion date should be more like May sometime.

It may still be slowing down, though it's difficult to say by how much.
