What position accuracy do you need? The truethevote screen used additional data. As an example, you might say that 10 m is not accurate enough to prove that this was a mule dropping off ballots. But what if you have a cell phone user who goes from within 10 m of an NGO office to within 10 m of one dropbox. Stops there for 15 minutes. And then goes to within 10 m of another dropbox and stops there for 15 minutes. And then goes to within 10 m of a third dropbox. This is incontrovertible evidence that this is a mule from 10 m accurate data.
