Would it be possible to just get HTML with only neutral/positive strength DT2 members? Ideally in same format as DT1-strength.txt, but imagine that's too much to ask.
That requires analyzing the data already.... I may do it at some point (when I'm bored enough).
OK, maybe I'll wait for you to get bored enough at some point then
Not convinced I'm very good at the data refinement part...
Think I could do with avoiding 20K pages if possible, as not convinced my laptop will handle that.
My laptop has 20 million files, it's fine

It's not the files I'm worried about, it's importing into a spreadsheet. That's where it usually goes wrong if it's too much data.
Ideally it'd also only show inclusions/exclusions per member from DT1!.
I'm intrigued: it shouldn't be that much work to loop through 200+ weeks of data. I just don't have the time for it.
It's understandable. That's why I was thinking if the data was already refined to only DT1! inclusions/exclusions, it'd be a lot less data to parse (presumably).
But then there's still the issue of thousands of users on DT2 -1, that in all honesty I don't really care about either.
There's probably a logical way to analyse the data without it taking too long though I imagine...
