For those that apparently do not know JC well enough to know what his statement meant, I will translate.
"I have done multiple tests with two similar dps guns of the same weapon type (i.e. laser pistol). One of these was UL non-sib, and the other was L sib. I have conducted these tests keeping all things exactly the same in every test except which gun I have used. I have used ample amount of ammo to ensure an accurate result, and rotated between the guns every test, i.e. run 1: gun A, run2: gun B, run 3: gun A, etc, etc. Based on my profession level for these guns and the setup I used, and taking MU for the L weapon into account, the non-sib gun was relatively similar in eco, or somewhat better. I am not at lvl 70 profession level for hit or dmg for this gun."
How close did I get, JC?
