Any extra benefit to super-high initiative?

[Drac33]

Title, basically. By 'extra' I of course mean something beyond "you get to always go first in combat."

Like, I seem to recall that Accuracy has a little thing where any excess amount (over 100) gets added to crit. chance. So does Initiative have anything similar? Such as, if your Initiative is high enough (or at least high enough relative to your enemy/enemies) can you get an extra action per round the way a lot of bosses do?

Nope, just means you go first. No '2 turns in one round' like bosses for you.

Would be nice if initiative could have an small incrementing % (the more initiative you have) chance to do an small extra attack equal to the previously damage type dealt to the same target again.
That could similiate being so agile and really fast (compensating high initiative PC's) that you could sometimes slip in some extra damage against you current target (only single target Powers), that in an sense would count as an extra turn similation for the PC (instead of gaining an extra turn like bosses do).
