Hello mate,
Not a noob question at all. The AQ you choose in the table to the left does indeed affect the outcome in the drill table to the right.
Different drills train different attributes/skills. The training efficiency in top eleven is based on the average quality of each drill which is the average of all the skills a specific drill targets. The higher the average quality of a drill, the less efficient the training of that specific drill. The efficiency drops for every incremental 20 % added, starting form 1, 20, 40, 60, 80, 100 all the way to 180 which is maximum. Once the average quality for a drill hits 180, your player won't gain more from the drill.
The average quality level you choose depends on your resources. The higher the average quality you choose, the more rest packs it requires. I usually settle for 120, but sometimes if I want to target specific attributes more than others, I set the average quality to 140.
You could play around with this. For example, if you want to train Speed you could set AQ to 120 and train different drills that targets Speed. That way, you're able to increase the Speed attribute very much eventhough you're only training the average quality to 120. You could train Stretch first, then Long run etc etc.
Hope that helps. Let me know if you need anything else.
