I am still wondering if the 10 percent is a simple addition or a multiplication. Is it +10 or *1.1?
1 percent + 10 is 11 which really means a good chance against 30 plus quality. 1 percent*1.1 shouldn't make any difference.
You might want to try setting up your team earlier. I remember reading it somewhere on this forum that last minute changes might not be taken into consideration at times. So you might be thinking you got trolled but it's because the calculation for the game was based on an earlier setup.
