Man, I wish I could answer that. I am not sure, but I do think one begets the other and I think the MLC is in the lead.
Forgot to ask: you say MLC can beget WW, but not the other way around (which makes sense). So in some cases WW can occur w/o MLC. In that case, what drives the WW? If not MLC, what might a WW be motivated by?
