No, friendlies and assos, are separate features. I would count only the regular season with the main 3 tournaments, still not sure if apply the count for the 3 maincomps or separate League-Cup-CL because;
-any times we see Play-off rounds where for example, if we had a clear better team, and we have a closed score, the 2nd leg scenario "corrects" the differance.
-The "contributive players" if Im right, have a variation in ratings playing in different comps... like 6-7-6-8-6 , this would mean that counts the 3 main comps, otherwise, as Ive not paid really attention to this, it is posible that the game gives a "fixed" behavior for League, and then a specific one individually for a CL/Cup play off....
Friendlies and FAs have it's own specific simulator calibration, like the extra events, where we can see paranormal activity... lol
