“As I mentioned earlier, it turns out there WERE some matchups that were so close they turned things around due to discarded votes. These were the following votes discarded due to missing or incorrect verification answers (MOSTLY missing, more than half of those i had to toss simply had them not filled in at all or filled with ‘idk’s)
 
Rarity 19 / Derpy Hooves 12 (wouldn’t have closed the gap)  
Celestia 19 / Twilight Sparkle 14 (wouldn’t have closed the gap)  
Princess Luna 22 / Applejack 13 (Luna would have won by 1 vote)  
Pear Butter 20 / Trixie 17 (Pear would have won by 2 votes)”
