Same problem with my tournament.
112%, 119%, 127%, 128%, 130.5%, 133.5%, 141%, 143%, 144% and 145.5%
Currently it's
1. 145.4%
2. 112%
3. 144%
4. 128%
I'm the 112%. Ironically the 128% and I lead in goal differential. Problem is, as u said I'm the easy target when they need to steal a trophy because of my low quality. And with the weekend starting more time to login and play spoiler.
Fortunately 6 of them aren't putting forth much effort. I just need to figure out in what order to attack them so I don't have to launch an attack to steal back the trophy.
