It probably would. As someone below mentioned, as long as your intention is clear that's fine. In that case the one you marked as 1,000,000 would be taken as the last number on the form (assuming no other mistakes)
In the senate you're allowed three sequencing mistakes before you paper is thrown out.
Anthony Green's election guide is a pretty good starting point for those wanting to better understand our voting system. He also has pretty good guides of how much the voting has to swing for seats to change hands - Senate and House of Reps
One thing that suprises me about this is that there's no reference to this being a Google project on the front page. Is this a deliberate move to seperate it from normal Google activities? To give it more of a chance as something other than the latest Google fad? Any ideas? It doesn't even look like it's geared specifically towards web apps.
Will Joss Whedon be involved? It seems kind of pointless if he isn't. It was his skill that made the TV series what it was and I just don't see anyone else being able to pick up from him.
The other issue is that there is a lot of secrets still. Only Joss (as far as I'm aware) knows what they are and he had where the series was heading planned out. It's a nice idea in principle but without his involvement it would just be a game using the Firefly name to generate sales.
