Yeah, I misunderstood what you were saying. Now I see you want a general "default" vote. I think best coding for that would be for the post slider to "stick" where you set it so you could still vote higher or lower on each post individually.
Maybe even a text box in your settings to set "default vote" and your individual slider would always start there.
