I do have 285 positive and 3 negative feedback for the last 12 month. Today's morning old design shown proper number, 99% ('cause of 100% - (3 / 288 * 100 = 1.04%) = 98.96% = 99% - it's a simple math rounding rule, known from the middle school. But looks like eBay's "programmers" aka copy&pasters don't know that rule at all.

If you hover your cursor over the "how is feedback percentage calculated" link on your feedback page, there is an explanation of the math. Of the 285 positive feedback you have in the last year, only 270 are unique. Multiple feedback from the same seller/buyer in the same week only count once toward your percentage. So the actual calculation is 270 / (270 + 3) = 98.90%.

Nope, today's morning (and right after afternoon) it was exactly 99%! (what is actually correct)

And what do you mean by "unique"??? All feedback are unique, you can't leave 2 feedback for 1 sold item! And please explain, how 99% can be converted to the current value? Please don't tell me what my eyes are blind.

About 6 months ago, I negotiated a deal with a buyer for 18 individual items. After they received the package, they left me 18 individual positive feedback, but only 1 would be unique and figured into my percentage, because all the purchases were in the same week, from the same buyer. In spite of a large amount of time going into the order (including approx 20 back & forth Ebay messages between us). So I think that is an example, though possibly not what you were looking for exactly.

Here's that mouseover text from your feedback page I was referring to:

Your answers are on your FB page. There is a link below your Ebay ID that says "How is Feedback Percentage Calculation?" Click on that and you will see the information below. And yes, as FB is added and FB drops off [over 12 months old], the numbers may change. Right now it would be based on 2/20/2018 through 2/19/19. Tomorrow it will be based on 2/21/18 through 2/20/19. And so on as it is based on the previous 365 days [not calendar months]. I know others have tried to explain this, I hope this helps.
