I have something to add for 4), 5) and 6)
4)maybe you don't know if the oppo is playing high or low pressing but at least checking the tackles statistics will give you a hint if you have to use or not high pressing .
5) the same from above here , but referring to fouls.
6) more or less ... if your shots on target have a small percentage from total shots then I am pretty sure your oppo is playing mtm marking.
