If I have Novice Gerard in my hand early in the game, and quickly learn that player A has one Templar Novice crossed off and player B has one Templor Novice crossed off, I know I can eliminate all three Templar Novices.
...However, if I learn early in the game that player A has one Templar Novice crossed off, and then learn 15 minutes later that player B also has one crossed off, I need to somehow deduce whether they have the same Novice eliminated, or two different ones. It would be helpful if I could look at my sheet and determine how old my previous clue was, and whether or not these players have had the chance to share this information with each other or not. (Obviously, this is a simplified example, but hopefully you get the point.)
With a sheet covered in markings, it's easy to lose track of where and when I learned each piece of information, and this sometimes affects how I can interpret a new clue. How do you go about tracking whether a clue on your sheet is "stale" or "fresh"?
