I presumed you meant something more by Decisiveness, such as the 
appearance of a large victory and a mandate even if the people's will 
is divided.  Runoff scores better than Plurality on the Mandate 
standard.

Using only the Simplicity and Decisiveness standards, plurality 
scores very well.

pro {{Simplicity {{Plurality
pro {{Decisiveness {{Plurality
