Even with 40k a week scouting you won't get as much information as you like. For example i scouted 40k a week most of last season and got:
15 players fully scouted - position, age, box score, star rating (current skills), grade, potential rating (future ability)
24 players scouted once - position, box score, star rating
9 players unscouted
So you can see even with full scouting there will be holes. In my example there was 33 players who i didn't know there age or potential which are 2 impoirtant things you want to know.
