Hello, I don't want to extend this longer than necessary but I'll still reply.
There are instances where the 2x rule doesn't apply that's true. But it isn't a lot. And there are examples where it's consistent or doesn't contradict the rule. Example gohan losing to cell at half power but obliterating at full power. And examples where the rule isn't broken is vegeta vs goku where kaioken x3 goku is less than 2x vegeta but still beats him decisively but it's not a one shot victory. Because remember 2x is to cancel out the opponents ki completely and or not taking any damage at all so it's actually consistent and this applies for other examples as well. And while this may be for the barrier technique, the actual reason the barrier technique does this is because the ki is 2x the opponent and db wiki confirms this.
About the half 2-C stuff, we already came to the consensus that since we're downscaling from 2-C the gap is quantifiable between low 2-C of the GoDs and 2-C while the GoDs are unquantifiably above baseline low 2-C. So the difference between the GoDs and 2-C is indeed 2x and not unquantifiable but it's unquantifiable between the GoDs and baseline low 2-C.
I really tried not to write a lot but it's necessary to get the point across and there's more I wanna say, that's why I suggest opening that thread to discuss.

Plus, according to the current standards, the "half 2-C" is more like "unquantifiably below 2-C" since a combo attack doesn't necessarily double the power. So none of the quantification would matter unless you that standard.
