I thought that changes in DT1 will change those who are on the default trust lists, but changes to DT1 does not change our own personal trust lists or even the trust list of others because those one our trust list stay the same and those on other trust lists stay the same, absent manual changes, and the personal trust lists are not changed by members very frequently.
So if we have our trust lists set to level 2, then everyone on our trust list is level 1 and then everyone on our level 1 has their own level 1s, which would be our level 2, so in other words our trust would not be affected by changes in DT1, only by our changing our trust list or those on our trust list changing their level 1s.
Sure, I think that we may have several members who either don't have a trust list (so then their trust list would be default trust) or they purposefully include default trust on their trust list, so then the fact that default trust is within the trust lists of some members would therefore end up affecting the trust that shows for the members. I used to have default trust on mine but I changed that, even though I am pretty sure that several members who I trust have default trust on their trust list.
I am not 100% sure about the accuracy of what I am saying, so I guess I am asking rather than stating definitively.
I think what LoyceV said was that depending on who the members in DT1 are, then everyone's
trust feedback changes according to their own custom
trust lists.
I am underlying these lines because, from my understanding, what changes is the feedback that you see on your profile (i.e. the numbers X/Y/Z) and not the people that you have in your trust list.
In general, even though I wished this was simpler, I am still struggling with understanding how it works. The best approach I 've found was to try to do some experiments, like changing the trust depth on my trust list etc.
