@BlainCellars An accurate system yields high voter satisfaction efficiency and/or Bayesian regret. It is not so much about getting the right winner given the ballots but about getting this right winner in the case of strategy. @SaraWolk can point you to the VSE research showing how different systems do. Equal and honest are also about strategy resilience. Some of the other criteria are more straightforward like being expressive and simple. Those have an inverse relationship.
