Line 1:
Majority Acceptable Score voting works as described below. Technically speaking, it's the [[graded Bucklin]] method which uses [[Three-level ballots|3 grade levels]] and breaks median ties using [[Score voting]].
# Voters can support, accept, or reject each candidate. Blanks count as 2/3 of a rejection and 1/3 of an acceptance (so 75% blanks counts as 50% rejections).
Line 7:
# Highest points wins.
Step 2b probably doesn't matter, because any majority-supported candidate that exists would almost certainly win in step 4 anyway. But step 2b is part of Bucklin voting, which was used in over a dozen US cities during the Progressive era. Also, it lets you say the whole method in one sentence,
Here's a google spreadsheet to calculate results: [https://docs.google.com/spreadsheets/d/1siFG6XmOZokygY-86EhAKgv8YwzKtTET6AJopyXRqu0/edit#gid=0]. On page 1, it has some examples of how different combinations of ratings would come out, suggesting that it could work well in both [[chicken dilemma]] and [[center squeeze]] scenarios. On page 2, it has some hypothetical results for the Egypt 2012 election, showing that this system could have elected a reformer over Morsi, despite vote-splitting among the various reformers. IRV could have elected Morsi. (Note: the spreadsheet does not actually check step 2b.)

Memphis is explicitly given 0 by a majority, and is eliminated. Chattanooga and Knoxville are both given 0 by a majority implicitly, so they are eliminated.
If Memphis voters tried to strategize by rating Nashville
