I've never made a player injury prone, I always keep it at A
Making alot of turns while in posession of the ball, V-feint and basic feints help increase your agility. Always pressing special controls when you recieve the ball improves your technique, and making proper shots give you better shot technique, shot accuracy and shot power.
Proper shot is when you lay off the ball appropriately before shooting, have a 1-2 step distance between the body and the ball. This results in a powerfull, well placed shot even with shot accuracy, power and technique in the 60's
Using up all your stamina early on, but keep playing good and make an impact for your team will get you quite high mentality. I once got 92 Mentality, but using this strategy will get you in the 80-85 area at the very least. The drawback is that you start with 70ish stamina.
By conserving stamina and end the game without bein exhausted, you will get quite high stamina rating, but low mentality. Mentality is a better choice, because it affect how much being exhausted affect your abilities. 99 mentality, for example, means that you don't really notice any difference wether your stamina bar is full, half full or empty.
Having 80-85 mentality also mean that you often play full matches from an early stage in your career.
As for Passing, I always get crap rating in it, no matter how much and good I pass in the scout match. Same goes for response, it hardly ever changes based on the scout match. A high agility (90+) counter some of the effect of low response however, at least you don't notice it quite as much when in posession of the ball.
The overall Match Rating is not directly connected to your starting abilities, but it affect wich clubs want you after the scout match.
You can do everything I described above and still get a poor match rating, depends on how many errors you make during the match and if you score or make assists. A goal and or/and an assist in the scout match should get you a 7.0 or so even if you played rather poor and did none of the "excercises" I mentioned above. Your abilities will clearly reflect on that and be in the mid mid 50's and 60's across the board, not counting the stats that are a bit higher by default, like stamina and pace etc.
By doing the above execises you will get roughly the same abilities wether your match rating is 5.5 or 8.0 in other words.
This is my conlusions after testing extensively, I've played more scout matches than regular BAL matches. I often use different players, or reloading the save I always make just before the scout match etc. than to test what affects wich stats etc. for comparison.
I will test this "Injury B and C" setting theory of yours soon, it's not a bad thought in theory... but KONAMI is never logical either, so...
good luck
and hope to improve
