i am still not sure I understand it, but I may not really need to. So using some real numbers and fake ones.
Pre HF20 Whales 75% of reward pool everyone else 25%. So whales get $75 and everyone else $25.
Post HF20 Whales self vote 75% of the time everyone else 0% of the time.
Whales Reward pool 75%- 25% (for all the early self votes)= 50% of reward pool and everyone else 25% of reward pool.
Pre HF20 reward pool=$100 Whales ge $75 and Everyone Else $25
Post HF20 Reward pool=$100 Whales get $56.75 and Everyone else $43.25
The 25% that was returned to the reward pool goes to the all the others so would that be kind of close to what you are saying ?
Apples and Oranges, but is it close? Can you show what it would be with the assumption I used of whales and everyone else above?
