I'm trying to plan a dragon crafter scale set, but I'm missing the rather vital information on what they changed 3:1 skill to from the old 1467 value. My best guess so far is that it's somewhere between 1200 and 1300, but that a bit to big a range?

Is 3:1 always 50% between min and optimal?

That would make it 1288 or 1287 depending on how they round.
