Forum:Math QOTD: Recoil

I've partially gotten my head around damage and accuracy. Clip size and fire rate are mostly self-explanatory. Elemental effects are iffy, but I'm working on that. However, there is one other noteworthy variable with regard to weaponry that doesn't even appear on a weapon's pane -- recoil.

Now, I understand what Recoil is, literally. That isn't in question. But how do we know how much recoil to expect? The only thing I can find anywhere on the wiki about recoil is that Dahl weapons supposedly have less of it. That doesn't tell me how much to expect, or how it differentiates by weapon type (or sub-weapon type for that matter.) For that matter, it doesn't tell me how recoil actually behaves. And if I have "50% recoil reduction," that cuts the kick in half, right?

Lastly, does Sniper Rifle sway count as recoil? It's kick from the gun that causes you to be off-center after a shot, so one would think so, but the fact that it's worded differently in proficiencies and such makes me wonder. I mean, there aren't any automatic snipes out there.
