Hunter, same thing was occurring in the last 3 tournaments my association played in.
2nd weekend:
One 7*, one 6* and two 5* associations
3rd weekend
One 6*, three 5* (One of the 5* manipulated the draw with 1* teams, and after the upgrade were equal to the 6* in average quality)
4th weekend
Two 6* (my assoc = 117%), two 5* (Same 5* we played the weekend before, and they again upgraded to being equal to the 6* non manipulators)
This weekend
Things look normal.
The impression I got was that any quality below X (maybe 80%) was being excluded from the calculation for the draw. All 5* groups we encountered had teams that were below 5* average. That's why I think it might have been taking the average of only teams above a certain unknown %.
I can only guess this update was designed to force these lower quality inactive groups to play up as a means of minimizing the effectiveness of sandbagging in associations. Sandbagging means to purposely play at lower quality (such as 5* quality average), to get grouped into a pool of potential opponents that is more likely to lose 0-36 than those in other pools.
