9 is correct as 11 would be your overall trade score, when you would have dealt with same seller again, a rating msg would be displayed but it won't be added to your trade score.
For example if you dealed with Janasheen for the very first time then a trade score would be added to your tradescore, but if you deal with him again some time later and you recive a trade score, then it won't be added to your trade score unless a negative feedback (which is displayed on your post but it would be counted on your overall trade score).
