Information 'snagged' from a comment on AuctionBytes, on how to calculate a DSR score left for an individual transaction.

I just noticed that now when you go to the Seller Dashboard screen, at the top where your DSR 30-day scores are located, there is a link that says "see your reports". I had never noticed it before. I clicked on it, and it's a report generator that ebay has created to allow you to view your DSR scores for your transactions. However, you can't view a single transaction, all you can view is averages. BUT, you can 'trick' the report into showing an individual transaction...
Go to create report>report type>item numbers. You will need to enter 10 item numbers here, no less. The report generator will collect the data from the 10 items you listed and return your average DSR score for those 10 reports. If one or more of those transactions didn't leave DSR scores your report will be returned as incomplete. That means you'll have to take one or two numbers out and replace them with new ones.
So, what I did was I started putting item numbers in, in batches of 10. After a while, I found a batch of 10 that gave me all 5 stars across the board. Now, all I have to do is save that report, and every time I receive a new feedback, I replace one of the item numbers with the new number, and voila! it tells me what I received by looking at the average.
You already know that you received nine 5-star ratings. So when you look at your average after replacing one item with a new item, you can tell what your new buyer left.

If you still have a 5.0 - your buyer left a 5 star.
If you have a 4.9 - your buyer left a 4 star (9@5=45 + 4 = 49 = 4.9)
If you have a 4.8 - your buyer left a 3 star (9@5=45 + 3 = 48 = 4.8)
If you have a 4.7 - your buyer left a 2 star (9@5=45 + 2 = 47 = 4.7)
If you have a 4.6 - your buyer left a 1 star (9@5=45 + 1 = 46 = 4.6)
If your report gets returned incomplete, that means your buyer didn't leave stars, or didn't leave stars in every category.
The hardest/most time consuming part is trying to find 10 transactions that all left 5 stars across the board. That took me about 20 - 25 minutes of plugging in numbers because a lot of people apparently don't use the DSR score ratings. But once you figure that out, you're good to go and can figure out what ANY other transaction/buyer left for your DSR score.
