The curve is superlinear at every point (adding 1% rshares/votes adds >1% share of the pool), however it converges to linear.

Ok, so now the curve resides below linear and moves towards it.
That isn't sublinear?

At this point, this is better than nothing.
Maybe it brings balance to a highly contentious debate.

The devil will be in details that won't be readily apparent for some time after the fork.
Does 7 days balance the moving parts of the math, or will it potentially take longer?
