I think it should be Net 1 but with 2 inclusions minimum (i.e. like the current formula but bumped up by 1).
I've voted "None of the above", because I agree with this.
I've said this before:
I've said multiple times before: DT2 members should require to be included by at least 2 different DT1 members (maybe even 3) in addition to having a net positive number of inclusions. This removes all the "soft" inclusions as well as removing the issue of people artificially inflating their own trust scores.
I used to browse the forum on occasion with the ;dt tag appended to every page, because sometimes it is useful to see what the vast majority of other users are seeing. I don't anymore, though, because DT is a complete mess. The number of users on DT2 with a single inclusion which have been included for all the wrong reasons is far too high, as Loyce's numbers above show.
