This has probably been suggested before. If so, just consider this another vote for it:
When viewing an individual player's data, it would be nice to be able to see a line graph of his opponent's rating for each of his victories (ie. ratings measured on vertical & game#s along horizontal). A time-out victory could be a different colored point on the line. Similar lines for each of the player's losses & draws might be put on the same graph or viewed separately if too cumbersome.
This would help easily spot the types of info that it currently takes several minutes to research. I think this would be especially helpful to clan leaders in setting up challenges.
