That's because it's not 100% clear, even to us. Think of it a bit like a bunch of people pulling stuff out of a burning building. [0] We know there's more to be saved, because we can see more boxes in the building, but we haven't taken the time to see what's in the boxes we already have.

Yahoo aren't making this easier, either. (Blocking our efforts, unreliable servers, limiting what can be downloaded, providing incomplete archives, etc...)

Once the dust has settled we'll be able to start going through what was saved. There have been a lot of really interesting aspects to this project that I hadn't encountered before, and I hope to document them when I have the time.

OP here. Ok, thank you, this is the kind criticism I crave!

I suppose by "vague" you mean there weren't any hard numbers.

Well I kind of linked the archive team tracker but you had to do some clicking to find it, and unfortunately I didn't have a statistic on the SYG's progress at the time of posting. However since posting I do have a rough idea of things:

Archive Team's own Tracker reports 2.76 TB of data to have been saved. The SYG team hasn't fully tallied up their data yet, but have counted the number of groups they've retrieved and/or are retrieving from to be around 123K.

I have since inserted this data into the post and would like to thank you for your brutal honesty :)
