First, you don't compensate left and right alternating recoil patterns, because the weapon will fire any number of rounds in one direction then suddenly switch direction for any number of rounds. It gets worse with higher RPMs and greater recoil values. Second, a lot of the misconceptions are born from not fully understanding the power of attachments, and distances people REALLY engage others over. Screw what the database and the in game tool tips provide, I'm convinced fore grips have a positive effect on vertical AND horizontal recoil. Also, even the SAW would be hard pressed to kill a target at 100m before they react to the incoming fire. Weapons were balanced around 60-80m engagement distances back in early beta, and while still dummy targets are a poor test subject, the Carv and a fore-grip are accurate enough up to 80m. It's a night and day difference over bare barrel firing through a 3.4x scope. At this point, I'd say the Carv could stand to have a 2x reflex, compensator, and maybe an advanced laser with no further adjustments, but the latter two are based on hypothesized values regarding grips, lasers, and the compensator, so I won't say them here just yet. I know how the rumor mill works, and the people on these forums argue with their head more so than with their brain. And really, I'll be the first to own up to a simple fact: vertical recoil is a subtle <=> horizontal element if you don't pull back in a perfectly straight line.
