I think it's a combination of that AND the predominate MC forcing directing what opportunities for phasing there are, west and east of this region. That MC forcing is a Deconstructive influence on NE US phasing, which overlayed onto the overall trend for less phasing is BAD news for us. I'm confident the MC forcing will shift eventually...it's the overall trend for somewhat less phasing that probably won't.
Least of all, there is some bad luck, too...but the majority is more than that.
