Delegates are paid that 70% *over many years*. The delegates will not keep it! They will give it away or spend it on things. And it's not 101 individuals, since delegates always change.
You can always *force delegates to burn it* to keep your share.
You could have delegates have 1% if you wanted.
AGS + PTS still has about as much as delegates after 1 year, and that is if every single delegate has 100% pay rate. Most delegates will not be able to get away with this.
