I'm not entirely sure that's how the trust system works, and it's very confusing so I can't relaly be bothered to learn how it actually works...
I do know that Jet Cash got a positive trust rating from Vod when vod had a higher trust rating so he got a 5 next to his trust score, I, however, got a 2 which I'm guessing means vod lost some trust ratings along the way? Hence why I can't be bothered learning how the system works because it's too confusing too... I mgiht ahve calculated wrong somewhere also...
I also never have seen someone actually creates a informative information about how the Trust System really works. Aside from the brief explanation from theymos himself.
I somehow quite get the idea tho. If ever that Blazed will remove mexxer-2 from his DT list then mexxer will just have to be a normal user not on the DT. By that said, mexxer-2's tagged will just go to untrusted list feedback to that certain user.
I will give you some example that I hope you will get.
TECSHARE This user used to be a part of the DT list of theymos you can view that here
https://bitcointalk.org/index.php?action=trust;fullTECSHARE tagged this user
https://bitcointalk.org/index.php?action=trust;u=34020 for some reason. Yet you can't see that this user got a negative trust rating since tecshare is not a part of theymo's DT list anymore. Therefore if his tagged was legit then the account that TECSHARE Tagged is working around without having a trust issue.
While in your cased why you only have 2 in your rating while jet cash has 7 on it this is "my logical" explanation for that.
Based on the explanation given by theymos which is
The first number is the user's trust score calculated based on how consistently they've received positive feedback. Probably no one will get a score above 0 until the system has been around for at least a month. The second number is the number of reported scams.
Since Jetcash received all positive feedback not just by VOD. Even if only Vod's rating was trusted the positive feedback i guess from the other users somehow affect the calculation.
While in your rating you received an equal 3 positive Untrusted rating and 3 negative untrusted rating which is in my opinion equates to 0 value. That is the main reason why you can only see Vod's positive feedback in your rating.
Tho mind that other users view in your rating might be different. For example someone added you to their trust list so their view for your rating will be higher.
