Im assuming the "1" and the 10 and such here aren't going to be actual ones and 10s.... theyre going to base it off some meaningful amount of SP. Its tough to say when we don't know where thats at. Which is to say, i think we're seeing the shape of the curve here, not its magnitude.
This is also significantly effected by voting habits (which could change with the new rules).
In terms of the actual amount of curation blogging rewards you assign, it might very well be that some users will see a negative impact on their influence from not splitting up their vote now.
