Without knowing what your Ebay ID is, we can't see exactly what your situation is. However, I suspect the 1000 is the total number of transactions you've had, and the 982 is your actual feedback score. Often people neglect to post feedback on all their transactions, leading to the different figures. In my own experience, people only leave feedback 70% of the time.
