That topic also doesn't have DT2 strength as far as I can tell.
I was more thinking from 200+ weeks of data already stored at https://loyce.club/trust/, then DT2 strength per week could be calculated from:
DT1! inclusions - DT1! exclusions = DT2 strength
Ignoring (
(I realise this would also calculate DT2 strength for DT1 members unless an additional variable was included, but that wouldn't be an issue)
Anyway, was just a thought, not much else.
Edit: Just realise my theory is flawed, as would only include DT2 members who have created a custom trust list in past 4 years.
