I might have left some stuff out of the description.
As there are some if Statements in the Spreadsheet that I don't like
having, for theoretical reasons. But, I do like having for practical
reasons.
But regardless the Mars result can easily Fall below 45%
here is how.
1. Assume Mars = YES votes
2. Clear All of the Column "F" Labeled Results
3. Enter 44 in in Cell "F5" (vote #1)
Done
The Part I didn't describe was a provision saying that if the returned
result from Referendum N is greater then the calculated score then the
referendum result replaces the calculated score.

I don't see how this is possible?
could you give me an example?

yes I agree this is possible. even useful.

interesting, would your real time elections have some form of "leak" to
them?
or would the persons vote stand until they changed it.
this a very interesting read on Proxy democracy that might be similar to
what you are thinking.
