I think I do. I would characterize the results of our voting in this way. It was sufficient to accomplish the unfortunate end result ratifying CBA 2015.

sig·nif·i·cant
/siɡˈnifikənt/
adjective: significant

1.
sufficiently great or important to be worthy of attention; noteworthy.

I would not characterize it as "significant" because by itself it is not. The result was significant to all of us, but that doesn't mean the vehicle of that result is as well. The outcome would have been the same if the majority had been a single pilot. It's a binary event. Yes or No.

If one desires to claim a majority is significant by virtue of the magnitude of one side of the result (the only way it can be "significant"), I suggest majority of 1 pilot or thousands might be viewed as significant. 7%? Not so much.
