It's not that kind of vote. You vote satisfied to tell them you approve of the general improvement concept, and then you use your comments section to tell them what would be even better. I am saying if you vote not satisfied, you're saying go back to the 2014 version no matter what's in the comments because they won't proceed without at least around 70% saying satisfied. With a satisfied but not very satisfied vote, they will read your comments and may make it even better.
Given that, a satisfied vote is your best bet if you think it was an improvement.
