Well, typically, I try to cast out the X-number of songs that votes are allowed, so for the first round of TA, people will vote for 7 songs, so I will eliminate the 7 songs with the most votes, unless there's a tie along the way that results in either 6 or 8 songs. In which case, if the 8th (or above) tied song yields more votes than half the number of voters, they'll be eliminated anyway.
For example, let's say the 5 NOMAC tracks all go out, but then 3 more tracks all get 21 votes, and there are 40 voters. Those three tracks, in addition to the other 5, will all go out, resulting in 8 losers in the first round. It will vary by round, of course, depending on the results, but it should help expedite the process of elimination given that the album has 34 tracks.
