average opponent overall versus avg opponent when i win or loose

how is it that some people have average opponent of 1164 say, and the avg opponent when i win of 1333, and avg opponent when i loose of 1364, and avg opponet when they draw of 1360.  how is this possible if their overall average opponent is 1164?

Being an American your english is not the best here.sorry couldnt get ur question.

I have noticed that as well. The overall opponent rating average seems to differ way too much from the other averages (when I win, lose or draw). In my case the average opponent is of about 1620, while the other averages are all above 1660. There seems to a problem with these calculations.

i wonder if its based on a different time table
