Relatively new to this game and trying to figure out how the strength/quality thing works.

QUESTION 1
If my player/team has the following stats 100 % (22), does the
- Percentage (%) indicate relative strength to the current level (team)/roster (player)?
- The number (22) indicate absolute quality?

QUESTION 2
Upon promotion, do you only lose 20 % (relative quality/strength) or do you lose something from the absolute figure (22) as well?

QUESTION 3
When you lose 20 %, do the skills drop as well? If so, shouldn't the absolute figure (22) drop as well? If the answer to Question 2 is that "you lose from the absolute strength", then I have my answer.
