In the US, at least, we tolerate a fair amount of error. See the WI recount this election, which exposed the totals to be off by over one hundred votes. I'd be willing to bet if you recount again, it'd be off from that total as well. It isn't absolute is my point.
The electoral college introduces quite a lot of error, but people don't seem to care enough to change it.
Further, our first past the post election voting system is especially brittle AND the window for detecting and correcting errors is very small.
If the United States were to adopt one practice from the Swiss government, proportional representation might do the most good.
