whats vertical convergence?

Too bad we dont have this graph in the game yet.

Ah, awesome! Yes totally forgot about the arch. Anyway, if you knew the range and the trajectory of your ammo you can actually set the bottom range to very far and it would need to fire upwards to achieve this convergence point. So if you look at the graph and you know the elevation required for the set distance and where this intersects in the area close by, you'd be firing upwards with precision (or just use the tracers) .What is great, is that you don't actually have to worry about the top guns' convergent point aligning with this far point since you can set each gun's convergence point separately.
Have I done right?
