Its my table! What info are you confused about?
Why the different username? The table was created by pwnsweet and corpsreate who posted it on this forum a while back, you can even see their watermark is on the table.

One thing the chart lacks is recoil values.
I immediately spot one mistake:
The SWAT556 doesn't 4 hit kill on extreme ranges.
It kills in 5 hits.
But then again, recoil stats plus that table allows us to determine the best weapons in the game:
Tier 1: M8 (With selective fire, the gun does everything best)
Tier 2: MTAR (Damage), M27 (Accuracy), SWAT556 (Killspeed), Type 25 (ROF)
Tier 3: FAL, AN94
Tier 4: SMR, SCAR-H
Tier 1: Vector (Accuracy), Chicom CQB (Accuracy), Skorpion EVO (Sexy), PDW57 (Range)
Tier 1.5: USMC, MP7
Tier 1: Ballista, DSR 50
Tier 2: SVU, XPR-50 (One has bad multipliers, the other has horrible sway)
Who uses LMGs anyway??
HAMR, I guess.
I can't recall getting killed by other LMGs than the HAMR and the standard class LMG.
They are all horribly underpowered so I don't even bother to rate them.
