For 29s, look at NXT. They don't play in any top brackets but beat the living [Censored] out of everyone they play. As a result, they are currently ranked 6. If you have watched them play, they are a solid team but nowhere NEAR a top 10 team.
If they had played in top brackets or better tourneys, they undoubtedly would have a much worse ranking.
A previous commenter flagged NXT and Steps as mathematical anomalies when they were both in the top ten. He predicted a rapid and deep decline in both ranking and rating after one more game was played. It happened for Steps. The same is in the near future for NXT.
