sure it's likely that the 25% that don't agree with will fall into line, but can we really call 75% a successful agreement
lets all vote 90%
I don't think we can call 75% consensus. That's more like 50% or so + a lucky streak. I believe consensus is basically paramount to virtually all other concerns in regard to the protocol. And that certainly includes a contentious debate about block size.
I concur -- 90%.
91% of the poeple disagree with you.
so in by your very definition we have reached consensus that 90% can't be considered the threshold
HA put that in your pipe and smoke it

wait no thats the 95% option that has 91% of the poeple disagree with. never mind whatever 75% all the way
