Also, I think you forgot to take into account the multiplier. The ADS multiplier for the Kobra sight is .5, in BF4 it's .6. I tried those numbers, but I felt the sensitivity to be very high, and not at all like BF3. What I did yesterday was multiply the hipfire quantity by .5, and then I plugged that number in to the calculator, and used a conversion from the kobra sight in BF3 to the kobra sight in BF4. As for the conversion setup I used 0%. That's what I did yesterday. I'm not sure if I did it correctly, but that's what I did.
