No the last couple months they held serve. Over the last 9 months, it is a huge difference.
They key is for the smaller accounts (from Red Fish to Dolphin) to keep adding SP. This will overwhelm the system with their numbers and since 75% of the reward pool goes to authors, that means they can make big gains.
Ultimately, I see the chart completely reversed over time. The Red Fish will end up with the most SP collectively and the whales the least. It might take 3 or 4 years to get there but another 100K daily posters in the smaller categories would go a long way to changing that.
