Same scout, same player.
Report Card only.
Used FM Modifier to alter the scouts CA/PA value but none of his attributes. The time frame was short enough that the game did not automatically adjust his attributes to reflect his new edited CA when I got the report card.
Same game reloaded from same point rather than changing his CA in the same game to negate the possibility that getting consecutive report cards results in more information being revealed.
Look at the difference in the information obtained from a report card only by varying CA:-
Reputation(s): 7000; CA 140, PA 140

Reputation(s): 7000, CA 195, PA 195 (no change in visible attributes as all I did was change CA and PA using FM Modifier).

Whether or not the change in CA will cause the game to adjust his attributes automatically is irrelevant as it clearly shows that the game code references CA and PA (or maybe CA only?) in deciding on how much information to reveal. So if you take two scouts with identical CA but a different distribution of attributes you’ll get the same level of detail.
To answer your question there is no relevant attribute, just CA or PA or a combination but most likely CA alone.
