1. They said it's based on last 3 weeks. My current theory is that since it's new, it didn't have any past data. As soon as the first fight happened, that's ALL the data from "last 3 weeks", the average of which (average of 1 or 2 fight only) was used to determine it and it was too few and thus the 3 land. That's just my theory.

2. I would assume that it would shrink based on BOTH groups (either the higher, the lower or the average) and be the same size for both side. And until I see evidence to the contrary, I'm going to say that's how it is. Because like you pointed out, it would be stup1d otherwise. Note that there is ONE person who said that their group had 3 while other had 6, but his later screenshot CONTRADICTS his claims (specifically, it was taken AFTER the fight have begun, and the opponent did NOT have free points)

3. I totally agree with this.

4. I would assume that they want to make it so it's power over strategy, so that ptw will... well.. win. You know, the thing they paid for? Also, are you high? We have no rights
