Averaging shots for higher accuracy?

It's generally accepted that nerf arms have such a bad accuracy that we don't even use the word 'grouping' (do we?) to describe it. That is because mechanisms and ammo are too full of subtle imperfections keeping the shots from being anywhere near identical.

So, I've been thinking: what if we had a way to average out those imperfections, could we get more accurate shots?

I am thinking, for example, 3 barrels shooting at the same time, with 3 darts tethered to each other. Could it be that, as one dart veers off left and another right, they would end up forced to follow their average trajectory, which would be closer to straight ahead?
