I think this might be the thread that clairweber is refering to:
If it is, then I'm the one who's guilty of resurrecting the Box Stitch or Double Moss Stitch debate.
Personally, I think the difference in the stitch multiples is a bit of a red herring.
After all, I don't think anyone is going to look a a finish item, count the sitiches and say:
"You've got 100 stitches per row here, so you were doing Double Seed Stitch, as it's divisible by four. Then here you increased by 2 stitches, so it's not divisble by four, which means you were doing Box Stitch. Then at this point you increased by another 2 stitiches so you went back to Double Seed Stitch."
However, I do appreciate that they gave the instructions for both stitch multiples to get people on the right road.
