Hello, I have been trying to figure out how eBay calculates positive feedback. I know they say they calculate it by taking the total positive feedback in 12 months and divide it by the that number, plus the negative, and you get the total percent. I don't know if it's a glitch or what, because it doesn't match reality. For one thing, I look at the information window that shows how it's calculated and it says I have 44 positive feedbacks for the past 12 months, but it says 50 in the Positive/Negative Feedback columns. Where is the other 6 positive feedbacks I have that's not being included? I would have a higher percentage rating if it was being calculated by 50, instead of 44. Currently, I have 97.8%, it would be 98%. There's something else I can't figure out, my current rating was 97.9% literally two days ago, and now it's 97.8% today, what happened to the 1/10 (0.1) percentage point? This isn't the first time it's happened, my total percentage rating has been dropping like this on and off on it's own ever since I received 1 negative feedback months ago.
According to my calculation, if I had all the 1/10 of percentage points that has disappeared, I should have more than 98% like 98.2, and that's including the way eBay calculates my percentage score with 44, instead of 50 feedbacks, if was calculated by 50, it would higher than that. Also, when I do receive positive feedback, my percentage rating doesn't go up every time, only the total times I received any positive feedbacks does, which is currently 83, it has to be every other positive feedback I receive for the percentage to go up. For example, if I receive 2 positive feedbacks only 1 is calculated as 1/10 (0.1) of a percent, and the other isn't. Perhaps a person's positive feedback is worth 1/20 (0.05) of a percentage point and it takes two positive feedbacks to equal 1/10 (0.1) of a percentage point? In any case, it's as if I'm still being penalized.
