Thanks, I couldn't remember why it worked this way...

Personally, I've still got no strong opinion one way or the other, both ways seem to have advantages and disadvantages.

Given the way I suspect people mostly vote when they vote manually, I think the original way (full vote each time) with a 5 day interval would no pose any issues for people, so I wonder if this wasn't someone's theoretical concern rather than an actual complaint that led to the current operation.
