Here's a challenge (which may help to improve your own Trust list): check which ones of the usernames on your own Depth 1 and Depth 2 you recognize. Then check if there are excluded members on those Depths that shouldn't be excluded.
Chances are a small change to your own Trust list can lead to large changes on your total Trust Depth. If you want an update, let me know.
Example:
mine: even on Depth 1, I already have many usernames I don't recognize. On Depth 2, it's much worse. I would have expected the list on Depth 3 and 4 to get much longer, but the opposite is true. I don't think I recognize any of those users, but those Depths are irrelevant since I use this
Trust setting:
This is the default most users use.
