Particular methods

Please rate the following methods on a scale from 0 to 10, on merit alone. (That is, leaving the issue of public salability aside, how well will the method perform in a large, contentious electorate?)

The answers you give on your first pass through the survey need not be final. Please feel free to change/update your answers as many times as you like.
