Well the 5$ of SP is not that much, and we have only 70+ thousands account so far, so it's not that big user growth.
So in my opinion inequality will drop when the power-down will pass 5-6 more rounds (weeks for every account). So lets wait at least 2-3 more months and see how it progresses, I think its too early to tell now.
I agree @profitgenerator that it is early in the travels of these uncharted waters.
