Like I said elsewhere, most coupling examples I've seen make assumptions about which change path is the most likely. The ones you choose are not the most likely in my experience (at least for my domain). Thus, your "coupling" metric is not a slam-dunk free lunch. It makes assumptions that some of us question. In short, technical people will disagree about what decoupling option is the best, since they may conflict.
I've described some of this at:
Okay, I've fussed enough about coupling this week. This should do it for a while.
