I don't think that's true? We already know D is above our fee floor so if B with A is also above the floor, we want them all, but also if B isn't above the floor, but all of them combined are, then we also do?

If you've got (A,B,C,X) where B spends A and X spends A,B,C where X+C is below fee floor while A+B and A+B+C+X are above fee floor you have the problem though.

Is it plausible to add the graph in?
