You still have 2 neutrals and 1 negative within 12 months but… keep up the good work and you’ll be at 100% positive soon!
You might want to increase your chit-chat with buyers though, you’re only at 4 Stars for communication and that can lead to more neutrals or even negatives.
Good luck!
But yes, if a year ago, you had say 100 positives, and this month had 22, as a percentage, those 100 positives will fall off, and the 22 will not counter those three bad marks as well as the 100 did, hence, your percentage will go down.
